Alesis ProActive 5.1 not Recognizing Optical Conn

I'm using the Alesis ProActi've 5. Speaker system and the Audigy 4 Pro soundcard.
When connecting the optical cable from the breakout box to the Alesis controller (which has a coax and optical in) the Alesis system is not recognizing it. Although it does recognize the coax.
Can anyone help?
Thanx

To paraphrase the portion of the sticky above that is relevant to you:
Creative Labs does not make a sound card that ENCODES multi-channel sound into an S/PDIF output. All they can do is pass-through AC-3/DTS sound from DVDs and PCM (stereo) sound for other sources, such as games.
In other words, if you play games with multi-channel output, you must use analog/mini-jack cables to send sound to your speaker system or home theater receiver's 5./7. RCA inputs.
If you want realtime 5. encoding for games, so you can just use one digital cable from your sound card to your receiver, then you must look elsewhere, or wait for Creative Labs to release their DTS-60 ($99), which is an external device that takes 5. analog sound and creates a digital DTS stream.
If I were you, I'd ditch the Audigy 4 and get a

Equium A210-1C4 not recognizing optical disk drive

I have a Equium A210-1C4 which will not recognise the odd.
The drive has power and spins disks but does not appear as a drive in MY COMPUTER.
It also is not recognised in the Bios.
I have updated the Bios and tried to install the firmware but get message that the drive is not found.
I have tried is in another computer and it works fine.
Has anyone had similar problems and is there a solution?
Many thanks

> I have tried is in another computer and it works fine.
You have tested optical disc drive in other computer?
Anyway, if the ODD is not recognized in BIOS Im afraid ODD controller is defective. It is mainboard issue so there is no some kind of easy solution.
I don't think you can do much about that except to exchange the mainboard.

IBook not recognizing optical drivve

Help! My optical drive quit.
I was at a family reunion, burning a couple of cd's, when it wouldn't mount a blank disc anymore. Now it does not recognize the drive. With System Profiler I get the following for the optical drive:
M@TRHHT@ CD-RW BW,8022:
Manufacturer: M@TRHHT@
Model: M@TRHHT@ CD-RW BW,8022
Revision: BA00
Serial Number:
Drive Type: CD-RW/DVD-ROM
Disc Burning: Not Supported
Removable Media: Yes
Detachable Drive: No
Protocol: ATAPI
Unit Number: 0
Socket Type: Internal
Obviously Something has gone haywire. Does this mean a new drive or can I force it to rescan or something to get the right info from the drive.
Don

I have heard this is prevalent. My wife ibook 1.33 doesn't recognize the optical drive as evidenced in the System Profiler.
She took it to an Apple store while in warranty and they changed the hard drive?!
I knew that the communication between the motherboard and the optical disk was broken.
A friend has one and claims if you squeeze the case it will work. He put a C clamp on his to make it work.
My wife teaches at a college and she said that other students have the same issue.

Computer Not Recognizing Optical Drives

I put a LG DVD drive in the bottom slot yesterday and now my Mac's not seeing either optical drive. The eject button says "No drives" and there's nothing under ATA under system profiler. Both drives have power and can eject manually. If I remove the SATA cable from the LG, there's no change.
Changed both jumpers to cable select, and tried other combinations. Did an SMC reset. Put the Mac in target disk mode and ran disk utility from my iBook. I really can't think of anything else and it's driving me crazy. Does anyone have any other ideas?

Okay, I fixed the problem. Through some inane, non-Apple-like, non-intuitive nonsensical procedure.
The problem initially was that my ribbon cable had a tiny tear in it. This was caused by one of the three aluminum posts that guide the CD chassis into the Mac Pro case. Really, really bad design, because the cable is flimsy and it's easy to snag it on one of the posts because you can't see anything when you are sliding the chassis back in, it blocks your view. So I had to go to a store on the other side of town for a new cable, luckily a sturdy one is only $10.
So I had to put the new cable in, which is behind the fan. But another design flaw with the Mac Pro, and some of you already know this, is that the front fan assembly is a monstrous pain to get out. Once you work that thing out, all the while thinking, "I know I'm going to break this", you can't help but marvel at how great the G5 fan assembly was, you could pull it out just to vacuum if you wanted.
So after I put the new cable in, I pretty much ran into every problem anyone with a Mac Pro has had in putting in a second drive.
The first one was the Superdrive showed up in the eject menu, but the text was garbled as if the system was using some unknown font. Like in the old days when you had to disable a fractional font because it was taking over your internet browser. I tried to put in a Leopard DVD, and it asked me what I wanted to do with the blank DVD. It did the same thing with a manufactured music CD.
So I tried to flash the drive with the NEC version on the web, but I was told by the Terminal that permission was denied even though I was logged into as the root user. So I thought I'd play the shell game with jumper settings again to no avail. Then I thought, what about Windows, I'll boot into that. But it saw neither drive.
When I booted back to Leopard, the eject button in the menu showed no drives again. But Superdrive was listed in Apple Profile. So I exhausted any way I could think of getting the Superdrive to work.
So I unhooked the master IDE and hooked it to the LG. It popped up in both the eject menu and Apple Profile. So I took the chassis out and swapped the drives. No sooner had I started back up again, then both trays ejected. Only the superdrive was listed under eject in the menu, and it wouldn't shut the tray. LG wasn't listed at all. When I pushed either tray in, they both opened.
I'd already changed jumper settings maybe 20 times in the last few days (they both were on cable select), but I did it one more time, and now everything is completely fine. I set the LG as master and the superdrive as slave.
However, they won't be allowing Macs in the mental institution I will surely be going to now.

Early 2005 G5 not recognizing RAM, optical door not opening

Hi,
I recently received a Power Mac G5, Early 2005, Dual Core 2.0 GHz, 1 GB RAM, 250 GB HD, running OS 10.5.8.
I decided to invest in this machine, so I ordered a paired 1 GB RAM (for a total of 2 GB RAM) from OWC. Then when trying to install software, I found the computer's optical drive door does not open at all. I could hear the optical drive trying to open but figured it was old and defective/worn out. So I also ordered a new optical drive from OWC. I also made sure to order the correct screws that OWC recommended for the optical drive too, as my original optical drive was a Sony and I saw there are some issues with the screws or height.
I installed the 2 x 1 GB paired RAM, and the G5 is not recognizing the RAM. In System Profiler, the slots show as empty. The RAM did not really click in like other RAM I have installed on my PowerBook G4, my former G3 Beige, and my former Power PC 6100. The hinges on the sides closed but not quite all the way, so I figure OWC sent me the wrong RAM and removed them before RAM issues start. I also noticed the RAM is slightly taller in height next to the original RAM.
The new optical drive installed fine, with the proper screws. However when I try to open it using the "eject" on the keyboard, the optical drive does try to open but the exterior door on the G5 case itself is not opening. It does show up in the System Profiler. When I had the G5 open and no optical drive installed, I doublechecked the exterior optical drive door with my finger, and it would open from the inside of the case poking my finger out, but not from the outside poking in.
Also, I noticed that the Model Identifier doesn't quite match up with the specs at OWC, Crucial, or elsewhere. According to the specs I should have 7,2, not 7,3? I ran the serial number at the Dutch website and also here at Apple, and both have said Early 2005. Is this why I may have the wrong RAM?
Model Name: Power Mac G5
Model Identifier: PowerMac7,3
Processor Name: PowerPC G5 (3.1)
Processor Speed: 2 GHz
Number Of CPUs: 2
L2 Cache (per CPU): 512 KB
Thanks in advance for your help and advice.

The RAM should fit then, it does snap in, but not always easily!
I couldn't get the last pair in until I laid the box on its side. For some reason, when it was upright I couldn't get the DIMMs to fully engage the socket. Zero insertion force it definitely ain't!
I see the OWC price is now about $3 lower than our local good supplier down here. I'll limp along on what I have in the machine now; it seems to work pretty well and three days after maintenance (DW, of course) and reboot, I still have zero page outs, which is a good sign, I guess.

Optical drive not recognized as an ATA device in Apple profiler

The dvd drive is not recognized any more in Apple Profiler (nothing under ATA) and the CD or DVD are not recognised neither. I can hear the drive is working but that's it. The problem happened just after I upgraded to 10.4.10. Any help would be welcome!

You will want to ensure your USB DVDRW drive is properly connected to the Windows 8 VM in question.
To check this you will want to use the Vmware vSphere client to connect to your Vmware ESX/ESXi host.
Next, you will want to edit the settings for your Windows 8 virtual machine and check that you have added a USB controller and then connected the USB device to the controller. This is a manual assignment. If your DVDRW drive you wish to connect is actually
connected via SATA on the motherboard of the host then you will want to go through the same process to ensure the CD/DVD drive of the host has 'connected' and 'connect at power on' selected under settings.

HT202274 Password change old password not recognized after 10.9.5 upgrade

God bless you, peace.
macbook pro 2012 user password not recognized after 10.9.4 too 10.9.5 upgrade plus tech work at apple.
I want to change user password, it is allowing me to get into user account and admin account on computer but I recently changed it for the tech work to be done. I would like to put the password back now to old password or a new one but... The few days old new password pre update and pre tech work is not being accepted to allow me to change to another password.
recent update, after 10.9.4 to 10.9.5 update and apple tech work done.
1. Tech work replaced optical drive,
2. 10.9.4 to 10.9.5 upgrade left computer endlessly booting up, then got into finder window tried to read backup drive and screen went to black curser and could not backup information as techs decided may need to be done before I left it with them.
3. Also track pad was not (is not again) selecting text to drag unless real hard press and then only intermittently would select text or just drop the selection (not hold the selected text after a long scroll select, did work at first after tech work but back to not working). It is still not responding easily when pressed, but it is much better, as they did something with software they said. Today While typing this I am trying to select words misspelled and it does not select them unless I press not as hard it is becoming the same as before I see now, sometimes less pressure is needed but more than should be used.
I noticed today after tech work The Spell check is not responding with a two finger tap on the red underlined misspelled words without multiple try's with two finger tap. The curser moves around after selecting words also, or when selecting words so hard the curser moves to another place not on the desired words or check box. The curser arrow tip should select the word but it does not recognize unless I put the tail of the arrow onto the word then it recognizes the misspelled word for spell check on two finger gesture.
It looks like I need to take it back, I tried to call and check to confirm if the track pad intermittently and curser adjustment was serviced. In order to verify I had called three times to get that information to no avail. endless looped in the phone que, one would answer take info and then forward me to a endless loop dial ing phone that never was picked up, supposedly at the Bay street store tech section. Phone voice mail from apple support status on the repair, ...Juliano from Bay Street Apple repair store Emeryville, ca left a voice message... just generically said optical drive replacement is successfulI, I noticed right away three items were to be addressed but only the optical drive was mentioned, so I called three times to try and verify the other problems. One whole minute just to select this text and copy it to notes for a backup. It would not select at first, then after selected it would not copy it, then it would not paste to notes, it paste the last cut and paste I did 10 minutes ago.
I do not have a easy excellent wifi connection for my wifi only phone and would prefer email or chat for repair help. apple Repair No: R142180337

Try running the combo update. It fixes more files/data than the App Store upgrade.

Hard drive not recognized in HDD bay.

Randomly, my laptop gave me the spinny pinwheel of death when I opened it, and upon restart, I got the good old folder with a "?" indicating there was no OS. Naturally, I booted up in network recovery, and low and behold, my SSD was not in the Disk utility list. I made an adjustment some time ago where I removed my optical drive, and installed the old HDD that came with the computer in it's place. I switched the drives, so that the SSD was where the optical drive should be, and the HDD in the drive bay. Upon startup, the computer booted up as usual from the SSD, and the HDD was not recognized. So from there I conlcuded that both the SSD and HDD are working correctly without failure. After putting the drives back where they originally were (HHD in optical bay, and SSD in Drive bay), and I booted up holding the option key, The SSD and recovery drive were there, but I received a prohibited sign (circle with slash) after a minute. Now it is not recognizing the drive again. I'm not sure whats going on, anyone hav any input?
Thanks

You have a faulty hard drive to logic board cable. Replace that and you should be fine and the drive put in the main bay should show up.

New Pioneer DVD drive not recognized in profiler

I have used these forums many times to solve my problems so a big thanks to everyone who contributes. I've never had to actually ask a specific questions until now so here goes....
I have an e-mac running 10.3.9. My superdrive started to get flakey (not recognizing some DVD's, spitting them out, etc.). I followed all the advice here but no luck so I finally replaced the original drive with a Pioneer DVR-118. My problems still exist and the system profiler is telling me I have a Pioneer DVR-106. Did I do something wrong on the install? Shouldn't the profiler recognize the new drive?
A big thank you to anyone who can help me through this.

Since your computer's Apple Hardware Test is on a disc and the built-in optical
drive won't work, you may have to see if an external optical drive capable of
being used as a boot, is available. This of course would be a FireWire combo
type drive that can read & write DVD & CD media and boot Macs.
You may have to see if you can archive anything worth saving from that eMac
and put it on media via another computer; if the eMac can be booted into
Target Disk Mode where it is seen by another computer as a FireWire drive.
In fact, you could see (in a reverse scenario, perhaps?) if another computer's
optical drive could be used by your eMac, if a second healthy computer is
available & then boot it into FireWire Target Disk Mode to see if you can use
the optical drive in there as though it were a peripheral. - This may not work.
I've not had to really use FireWire Target Disk Mode, but do have cables,
and an externally enclosed LaCie FW HDD which is partitioned for clones.
There are times where a FireWire externally enclosed superdrive is handy.
There may be some damage on the logic board or some circuit that does the
controlling of ATA devices on one of the buses in the computer. That would
be a possible cause of the issue. If the identity of this drive can be changed
by the user before it is installed, be sure that is set correctly for use in eMacs.
{The three eMacs I've owned, had issues early on and I got rid of them in mere
days of first purchase; at considerable distance and effort by me. Then I got
an iMac which was an unholy terror to debug after an 'authorized service' ctr
did their best to kill logic boards and sell me defective store-brand RAM they
were authorized to install in a place I was not. ThreeThousand Miles and Six
Months later, I finally got my iMac back, repaired. Only because Apple told
them to read my test notes - & just install the parts I said it originally needed.}
Do you have a second Mac nearby (presuming yes, and using it online) which
may be used to attempta further diagnostic or testing of the eMac?
Not sure if an Apple Hardware Test would be sufficient to tell the issues in
your computer; if you have a way to make use of it via external FW. Hope-
fully someone with more extensive eMac and drive experience will advise.
Good luck & happy computing!

Dc/dvd drive not functioning and not recognized in device manager after installing Windows 7 OS

I have an HP Pavilion laptop, model # dv9617nr, which was originally loaded (from the factory) with Windows Vista. I upgraded the OS to Windows 7 a few months ago, and initially, everything worked fine. Within the last month, however, my DVD/CD ROM optical drive stopped working and is not recognized in Explorer, and does not show up in Device Manager. I have tried a number of fixes from this forum and the Microsoft Windows 7 forums, with no positive effect. I should note that upon inserting a disc in the drive, everything sounds normal (device spins and the external LED lights up) but nothing happens and the unit shuts down.
I have no idea if this is a software or a hardware issue. I did check the HP website for software and driver updates for my model and the Windows7 OS, but HP has no update for this PC running this OS. ANY help is greatly appreciated.

Iphone 4 replaced dock flex connector/still not recognized by Itunes and charges very slowly

I have an Iphone 4 Cdma Verizon. Had to replace dock flex connector after replacing screen. The phone is not recognized by Itunes or the computer for that matter also when making or receiving calls , mic does not work unless i switch to speaker mode. Operating system IOS 6 .

DVD burner not recognized in Leopard by iDVD 7.0.1

Not exactly the same problem I found in my searches, so made a new topic.
Setup: G4 tower, dual Giga Design 1.8 GHZ, 1.5 MB RAM, Pioneer 109 burner.
System Profiler shows ability to burner everything including +r DL.
I had to use a 3rd party hack to get iMovie 7.1 installed. Leopard did not recognize my 1.8 processor as legitimate. It would recognize it if downgraded to 1.7 GHZ, but I chose not to do so. iMovie 7.1 (iLife 08) now launches and works, but I used iMovie HD to make this project.
1. I have burned other DVDs in Leopard with this DVD burner successfully, including a usable (proven) backup of my Tiger and Leopard DVDs, both DL.
2. I have over 100 GB space available on my Startup drive as well as 80 GB on another internal drive that is storing the iMovie project. The imovie project in question is 15 GB.
3. After creating the project in iMovie HD, I exported ("shared") to iDVD 7.0.1, chose a built-in theme and started the burn process. All was going well, so I went to bed. G4 set never to sleep for this project.
4. Next AM found that "error - .... disk not burned due to burner not recognized (error xxxxx). Didn't get the exact error number, but the iDVD project, when saved to Desktop was only 137 MB. The iMovie HD project is 15 GB, so iDVD should have created a project about 3 + GB.
5. Have NOT tried Apple Hardware test. Doesn't make sense to do so when the burner works fine in Leopard for other projects.
Is this problem due to iDVD 7.0.1 failing to be compatible with my G4 configuration like iMovie 7.1? Got no warning when installing or launching iDVD from iLife 08.
Any suggestions? I hope I've given enough useful info.
Incidentally, I'm not in a corner, as I copied the iMovie Hd project to a fW drive, and then used iDVD 7.0.1 on my MB Core Duo to render and burn it. Just want to find out what the problem is with my G4.

I'll try that. It may work as it is not iDVD making the determination if the optical drive is "qualified" but DU. As I said in my original post, I have burned DVDs in this internal burner using Leopard and a Finder Burn Folder. It is only iDVD that is between me and success.
I did manage to get the iMovie HD project burned using iDVD 7 on my Intel iMac. I will try editing another iMovie HD project, exporting to iDVD7, and saving as a disk image to a FW drive. I will report back the results, but it may be a day or two before that happens.
I should also probably try the same routine that failed on the chance that it was just a fluke.

IDE drives not recognized by K8N Neo 2 Bios: Revisited

I am truely reaching my wits end with this problem and I'm beginning to believe that I'm not alone in dealing with this issue. Let me recap. After building my new system around the K8N Neo 2 m.b. and a AMD Athlon 64 3200 939, (Winchester) cpu I booted for the first time only to find that none of my hdds were recognized. Optical drives yes but not my two Maxtor IDE drives. Initially no variation in configuration would get the board to recognize my hdds but then suddenly, for no apparent reason my hdds were recognized but try as I may I cannot install another hdd as a slave on IDE channel 1. If I attempt this the master drive no longer is recognized. An optical as slave yes but not a hdd. Keep in mind I am no novice although this is the first MSI board I have purchased. I have checked the cables, (all good), made certain that the jumpers were set correctly and have tested the drives in my other system and they are good to go. I even flashed my bios in the hope that ultimately it would make a difference. Since I had a working system and nothing seemed to be helping I decided to let it rest for a week. However, this weekend while installing a program that required reboot I discovered that the system was slow and it turns out that one of my drives had disappeared to XP. Rebooting, I discovered that the drive was not detected by the bios during the reboot, that is until I turned off the system altogether and did a cold boot. It worked.
I would just write it off as a defective m.b. if it wasn't for the fact that it has continued to recognize optical drives in all configurations. Can anyone offer any insight into this problem? This really makes no sense to me and I'm the type of person who wants to understand.

Quote from: Supershanks on 14-June-05, 05:49:23
How are your hard drives if you have no opticals connected.
HD are definately in IDE1 ??
Makes no difference; with the opticals taken out no drives were detected. Install the opticals on either channel without hdd's and they were detected. Like I wrote, finally the board was able to detect hdds but put another hdd on the same channel and poof, neither were detected. Neither channel appears able to accept more than 1 hdd period. Right now I have 1 hdd, (boot drive) on channel 1 and a secondary hdd and an optical on channel 2. It works but what disturbed me was the fact that during a reboot this weekend my hdd on the 2nd channel was not recognized and continued to be not recognized until I did a cold boot. This situation makes my head ache Bad IDE controller? Bad BIOS? Weird IDE cable problem? Bad PS?

Mac Pro not recognizing bootable DVDs and Disk Utility giving odd results.

My issue is complex, but I'll try my best to explain it as I can.
One has been resolved it seems, but I am including it so that the whole issue can be seen in context.
Friday, May 16, 2014
Last night, after rebooting my Mac Pro from my Bootcamp partition (I'm using Windows 7 Professional if that information is helpful) I received a kernel panic upon Mac OS X booting (Mac OS X 10.6.8).
My first action was to launch Disk Utility to verify the Mac HD, verify was stopped by disk utility citing that I should insert my Mac OS X install DVD and repair the disk.
I tried booting from my Snow Leopard install DVD. After the grey Apple logo appeared with the gear spinning below it remained for roughly ten to fifteen seconds (a little long) — then the Apple logo changed to. A grey prohibitory sign (circle with a diagonal line through it, the spinning gear remained. — I tried booting from the Snow Leopard DVD a few time, same result.
Following this I tried booting using Disk Warrior, same result again.
I tried booting both the Snow Leopard and Disk Warrior DVDs in both my upper and lower optical drives, with no change.
I decided to leave the issue and call Apple Support in the morning
Saturday, May 17, 2014
This morning I woke my Mac Pro from sleep, opened Disk Utility and tried verifying the hard drive to see if it was temporary — same result, 'please insert the Mac OS X install DVD and repair the drive.' — I also tried booting the install DVD again with no result.
I then booted my Mac into Safe Mode to check my hardware.
Upon opening Disk Utility and verifying my Mac HD — the result "Macintosh HD appears to be OK", rand the test again to see if this was an anomaly, but disk returned another pass.
I performed a normal restart of my system, although Finder was a little slower to load than normal, the system booted correctly. — I then launched Disk Utility and verified the Mac HD, it returned another pass.
This confused me, after a call to Apple Support the tech explained that 'sometime a Safe Mode boot will fix problems because it disables all non-essential processes when booting. — That makes sense to me.
However.
The issue of my Mac not recognizing bootable DVDs remains — it reads disks correctly, it just will not boot them.
Other steps I have taken to try and resolve this remaining issue.
1. a PRAM reset. — No change.
2. an SMC reset. — No change.
3. Removal of newly installed RAM. — I have tried both running the old and new RAM separately, no change using either combination.
4. Running bootable DVDs in different optical bays. — No change from both bays.
a. My upper drive is an MCE Blu-Ray/DVD combo drive, but I have booted from this drive before. (Less than six months old.)
b. My lower drive is LG DVD-RAM combo drive, I have also booted from this drive before. (Over one year old, replacement for an Apple optical drive.)
None of the above steps have helped, I still cannot boot from my optical drives — I always receive a prohibitory sign shortly after the Apple logo.
Other system information:
Mac OS X 10.6.8
8GB of RAM (4 x 2GB)
500GB Western Digital Caviar Blue HDD (less than a year old, boot drive for Mac OS X 10.6.8)
1TB Samsung HDD (for data storage and also containing Bootcamp partition)
2TB HDD (cannot remember manufacturer, contains Time Machine backups, as well as data storage)
ATI Radeon HD 5770 with 1GB of VRAM
Sorry for the long post but I really need to be able to boot from my optical drives.

Update: found an old Mountain Lion installation USB flash drive I created a while back.
I am able to boot from the ML USB flash drive, but am still unable to boot from my either my Snow Leopard Install DVD or my Disk Warrior DVD. — I have verified both DVD and they pass verification tests.
This leads me to believe that the problem resides either in the Mac, or in BOTH the Snow Leopard and Disk Warrior DVDs.
Since I am able to boot from a USB drive, I will look into the possibility of creating a bootable Snow Leopard drive, and perhaps also a Disk Warrior drive — at least until I can resolve the 'not able to boot from DVD' issue.
