Issues with External Sound Devices & others - 13" Late 2011

Good day community,
Out of curiosity, I run Diablo 3 on OS X and its been unplayable since ROS expansion, massive fps drops and crashes, Blizzard claims Apple stopped improving hd3000 drivers on 10.8.3, is this true? Also when I run the game through windows via bootcamp it performs better and doesn't not crash, is this related to hd3000 driver support still being improved in windows?
Other issues I'm experiencing, facetime most of the time fails if I try to pickup a call from the macbook, sometimes it notifies me of the incoming call (iphone 5s) sometimes it doesn't. Bluetooth doesn't work, not even with apple devices, I can't pair any of them. External sound devices such as m-audio fast track pro, native instruments audio 8 dj, allen & heath xone 4d, they all have latency issues and sound clips and pops, even with the onboard sound I experience this if I open a couple graphic editing software while playing itunes. Checked sample rate in audio/midi setup, drivers, firmware, everything seems up to date, I'm not using a USB hub, I updated to Yosemite from Mavericks, which was a terrible upgrade from Mountain Lion and it completely lagged the computer, so when I upgraded to Yosemite I ran disk utility from boot and apparently repaired the hard drive successfully. Performance is better but none of the above issues were solved.
So I'm thinking about formatting from scratch but wanted to drop a line here and see if others have any of these issues and/or some tips.
Thank you for your time.

Hi Lyndon4321,
I know that can be frustrating when using an external display, but take a look at the article below to continue troubleshooting. I would take a look at Reset the system and work you way down.

Ive got traktor dj studio for my mac and windows, but I would like to conect my mixer to my MBP, but I need 2 audio outputs, will the "iMic" work in this case(conecting 1 cable to my MB output and the other one to the iMic output)? or I need a external sound device with 2 outputs? in this case, does anyone know any cheap sound devices?

MacBook Pro 2.0 GHZ Intel Core Duo, 2 GB RAM 80 GB hard drive, Ipod nano 2 GB Mac OS X (10.4.8)

But the spliter will sendme both songs in the 2 cables at same time right?
I need to send each song to a diferent cable/output, I use 2 sound cards at my windows desktop pc, the one that came with my pc and a sound blaster live so the "virtual DJ software" sendme 1 song to the sound blaster and the other one to my other sound card, so both sound cards are conected to my mixer to each chanel, but dont know If the "iMic" its going to work that way using the output from the iMic and the other one from my MBP.....
Or other cheap external sound card, that provide me 2 outputs...
thanks for the help

External Sound Card Problems

I've been enjoying my HP dv7-1025nr for the past few months with no problems. I recently decided to get into home audio recording and purchased an M-audio profire 2626 external sound card which connects through firewire. I've yet to get any sound from my computer through the device. I have downloaded and installed all the latest drivers several times (both for the profire and every other device on my computer). I've also updated the flash bios for my hp (which i'm still trying to figure out why there's no "advanced" tab in the menu...other users have resolved irq issues this way and it's not even an option for me). I have reinstalled my OS (several times). The M-audio tech support suggested purchasing a dedicated firewire card with a TI chipset to solve previous connectivity issues, so I got a Siig 2-port ExpressCard. My current problem is that even with the profire set as my default playback device, there seems to be a problem where windows is unable to send it any sounds. If I try to use itunes or windows media player, the timer won't even start when i press play. Everything works perfectly when i change the windows default playback device to anything else (laptop speakers, spdif out or nvidia hdmi out). I'm confident that everything on the profire's end is working correctly and there must be some form of harware or software conflict (windows services or otherwise). Device manager doesn't show and irq conflicts but i'm wondering if there could still be one. Windows is recognizing the device and the m-audio control utility is working. The profire also works perfectly through my other computer (a gateway laptop running xp). I have spent 2 weeks trouble shooting this problem and have come to the conclusion it cannot be fixed through normal trobleshooting means. I need a programmer to help me out with this one. Please help.

External sound device stuttering

I have an imac (2011) i believe. I own an an external usb sound device, specifically a lexicon alpha. It has been working fine but recently it started to stutter when i try to playback. My internal sound is fine and I tried the lexicon alpha on a pc and it worked fine. Do I have a corrupt file or something?

usb sound devices are usb audio cards and audio cards require drivers
and if the device have a poorly written osx driver then that would happen
I would look into what audio chip lexicon use and check if I could use a driver
from another usb sound card using the same audio chip

Sound device problem in ZONE

I created a solaris zone for my desktop use, but the sound device was not avaialbe. I tried to export it from the global zone:
device
match: /dev/sound/*
then rebooted the zone, login it, found there were several files added in /dev:
lrwxrwxrwx   1 root     root           7 Sep 17 14:50 /dev/audio -> sound/0
lrwxrwxrwx   1 root     root          10 Sep 17 14:50 /dev/audioctl -> sound/0ctl
crw-------   1 root     root      34, 0 Sep 17 14:50 /dev/sound/0
crw------- 1 root     root      34, 1 Sep 17 14:50 /dev/sound/0ctlThe problem is: how to change the /dev/sound/* files for all users to read and write, permanently?
I tried the following methods but failed:
1. Change manually these files' mode to a+rw as root. But once I logged out the zone or rebooted the zone, the changes were lost.
2. Create a script in /etc/init.d/ and link it to /etc/rc3.d/ to let it auto execcute when boot, as below:
#!/sbin/sh
/usr/bin/chmod a+rw /dev/sound/*
echo `date '+%D %H:%M:%S' > /var/tmp/enable.audio.log
ls -le /dev/sound/* >> /var/tmp/enable.audio.logthe content of /var/tmp/enable.audio.log is something like:
crw-rw-rw-   1 root     root      34, 0 9月 17 14:50:30 2005 /dev/sound/0
crw-rw-rw-   1 root     root      34, 1 9月 17 14:50:30 2005 /dev/sound/0ctlBut oddly, the permissions of these files would always be changed back to the original state soon, automatically.
3. I added an entry in /var/spool/cron/crontabs/root to change the permissions every 10 mins, and it did work, strangely. However I think it's not a good method, because I have to wait for 10 minutes before I can login it (if I login the zone before the permissions were changed, the sound device will never work)
Thanks in advance.

It's probably /etc/logindevperm that's fighting you. Read the comments in that file, then you can modify /dev/sound in it.
The idea is that only the user logged in on the console would normally have access to the audio device and the frame buffer, so the permissions are reset at login.
If you're having folks login through a separate zone, this changes that assumption.

Looking for External Sound Device for iBook G4

Does anyone know of an external audio device similar to Creative Technology's Sound Blaster Extigy that will work with my iBook G4? I would like to record CDs played through an external CD player that has audio compression. Unfortunately the iBook lacks audio inputs. Thanks.
Don Squires

Perhaps this is what you're looking for:
http://www.m-audio.com/products/en_us/SonicaTheater-main.html
I had an Extigy with my previous notebook (presario 1500) and absolutely loved the sound I got through my creative 5.1 speakers, at least when my computer was working properly
I see the sonic theatre as the mac equivalent, although it doesn't appear to have a remote, oh well. I have no idea how much of the software will work on a mac, but it can't be too hard to find some good audio software.

Re: Satellite L650D-101 PSK1SE sound device problem

Hi, I have problem with my new notebook *L650D-101* short part. num. *PSK1SE* with *Windows 7 64bit* and with *sound device*.
There is sound icon in the system tray, but with red circle with white cross and this message (I have Czech language and translated form from our language is) "There isn't connect any speaker or headphones", but this model have an built-in speakers... And if I go to volume control option (right click on speaker icon and the last item) I see only one audio device: High Definition Audio (Digital Sound HDMI). I think this is sound card placed od ATI HD graphic card. 7
I can connect my headphones to internal 3,5 jack, but still have the same problem and still have the same message...
I tried to install the latest sound drivers , that I can find, but with no success. I tried to run every windows update, uninstall sound driver, no success.
Can anybody help me please?
Thanks a lot and I'm sorry for my English.

Hello
Do you use the preinstalled Windows version from Toshiba or did you install your own version?
As Akuma wrote check the device manager if you can see any yellow exclamation marks or unknown devices.
Easiest way to get rid of this is running recovery installation from Toshiba recovery disk. The original factory settings will be restored with all drivers and tools. After this everything should work properly again.

Problem connecting external sound device to the line

When I connect my Roland Sound Canvas (external MIDI module connected to the Game/MIDI port) to the line in on the sound card (Audigy2 ZS) but I don't get any sound from the speakers when playing a MIDI file or when recording. When I use sound recorder I can only hear what was recorded during playback. What do I have to do to hear the MIDI audio playing while I'm recording it's
I didn't have a problem doing this with a SoundBlaster Li've Value card.

Any standard mini-stereo jack, like on the end of headphones, should go in all the way. That port is meant for use with headphones, and powered speakers that have the same connector. It is not designed for a special short connector. If your mini-stereo to RCA adapter's plug is the same length as the plug on iPod earbuds, it needs to be inserted all the way.
As a test of the iMac's port, try using a standard set of headphones (or iPod-style earbuds) to see if you get proper sound.

Sat 1710: sound device problems

I hope somebody can help me out with a problem i'm having with sound on my satellite 1710/windows ME nd I really don't know much about comuters!!
I have only had this machine for a few weeks (second hand)and the only sound I can get fromm the machine is the start up bleep, and I am not 100% positive that there ever has been sound. Checking the sound option in control panel actually shows no playback devices in the sound playback preferred devices. I have removed the sound driver from the device manager and after a reboot a crystal soundfusion(tm) cs4281 wdm audio driver was installed - but no luck with sound i'm afraid. I'm presuming that there must be asound card if startup generated the notbook to auto install the crystal software.

Hi,
yes there is a crystal audio device available and it is normally detected by ME like in your case!
Firstly you should enter the BIOS with ESC after starting the notebook and load default settings.
Did you get the Toshiba recovery CD when you bought the notebook second hand? If yes you should recover the notebook and unless the audio device doesn't work after that it might be a hardware failure!

Sound device problems

I have a toshiba satellite a105 s4054. I reinstalled windows because of a major viurs. Everything works but the sound. It says when I go to the device manager that the device is working. No icon for sound is on the task tray either.
I have read some of the other comments and tried some suggestions but nothing works. I have tried to download other sound drivers from the download section but that did not work either.
How can I load the sound back on?

Sound Device Problem HP 510

Hi: I have HP 510 with windows XP SP2. I reinstalled my system some days back and the problem is that all the drivers are working except the sound. I tried to download the new driver from the HP Driver Support website, but in vain. The site link is broken or what but the download doesn't work. I also read on different forums and installed UAA but it doesnt work.
The installation always results in Failure...
Please help, I am really in a mess because of this...

External Sound Device MIDI Controller Garadge Band

I recently purchased a MacBook Pro, with the included Garage Band. I successfully attached an M-Audio Axiom 49 to it, and it has worked very well. Now the problem; I am trying to attach a Roland JV-2080 synth module to my Axiom 49 using a standard MIDI cable, then run the Axiom into Garage Band through the USB MIDI interface. I can't get any sound out of the combination, and I was hoping someone could help me out.

AppleCart12,
Thanks for the reply!
I too can't get the control surface buttons to work. I'm not giving up though. Here's what I found thus far.
1. There is free software from M-Audio, called Enigma (http://www.m-audio.com/products/en_us/Enigma-main.html) that allows you to edit the presets on the Axiom series. The only problem is that the Axiom can't send the specific sysex messages requires by GarageBand.
2. There's a free tool called GarageRemote (http://www.muratnkonar.com/otherstuff/garageremote/) that can work as an interpreter to translate other MIDI messages into the the specific messages that GarageBand needs. Unfortunately, it uses hex expressions and I haven't quite figured it out.
Bottom line? Out-of-the-box the buttons don't work and you can't remap them natively to what GarageBand needs. My best bet is that I can figure out the hex codes necessary for a work around.

Pavilion a1253w sound device problem and other

Have old Pavilion a1253w, XP ME. Device Mgr. shows two problem devices (yellow ?s w/ !s)...one multimedia audio controller, the other just below it just says "unknown device." They are both in a category named "other devices." I've tried downloading every possible available driver for this model, but nothing works. I could provide the entire system resource report, but maybe someone has a good notion of what is causing this problem. Have done all essential Windows updates. I had to re-install OS from non-HP disc and used the label OEM key to activate w/o problem...but pretty much all my original and HP software is gone except for the available drivers (not much). Any help appreciated.

Hi:
If you have a Pavilion a1253w, accept the agreement, download, unzip, and install the first driver on the list.
