Using optical connection...?

Right now I have my 4 G5s connected by a 1GB ethernet network and I get about real time compression when I compress a graphic intensive project.
I use CommandSoft's FibreJet as a SAN and it is hooked up with the optical cables to each of the Macs.
What I want to know is if I can use that 2GB optical network to cluster my Macs for network compression. I don't see a setting in QAdministrator, QMaster, Compressor, FCP, or any preference pane.
Even if there is no way to use the optical, I am open to suggestions as to what is the fastest and most reliable way to network for compression.
Thanks in advance.

Audio switching using optical connection

I am directly connecting to my 2005-era Denon receiver (AV3805, no HDMI) using an optical connection. With the ATV2 "Dolby Digital" setting to 'On', I can get Dolby Digital (5.1) from movies on iTunes, but I'm wondering if the Denon unit is capable of automatically detecting/switching between *Dolby Digital 5.1* and *two-channel stereo*, for example, if I wanted to also stream music. Am I missing a setting on the ATV2 that is preventing the receiver from doing this? Setting the ATV2 to 'Auto' does not seem to force the Denon unit to decide on its own. Thoughts from others with similar receiver set-ups would be appreciated.

Can you not configure the amp's input to automatically detect the feed?
I set the input to 'Auto' on my older Yamaha DSP and it switches automatically.
I don't think the optical feed itself can tell the amp what to do - it just has to detect what's coming in and respond appropriately.
For 2 channel audio AppleTV should be outputting linear PCM, but I believe the newer one adulterates it by up-converting to 16 bit 48kHz, whereas the older unit didn't fiddle with the sample rate.
I'm not sure either if the Dolby Digital setting in the AppleTV menus only affects HDMI output, whereas a surround track just gets passed though on optical if it exists, if not a 2 channel 48kHz 16bit bitstream is sent.

Connecting apple tv2 to a projector, but need to use optical from apple tv to connect to something, to get sound.. What do I buy

Ive got an apple tv, and a new hd projecter. I've now got a huge lovely picture on the wall, but I've zero sound.... The projector has no output for sound, and is conected by hdmi...which leaves me with one option. Using the optical out from apple tv, now i have no idea. Will this optical output work when hdmi is sending sound to projector ? What I need is the best option to use optical out.. I would have prefered a simple phono out, and then I can plug into a big active speaker im using in the room, I owne nothing with optical connections... So what do buy ? Ric

Ok, I will ask the question in another way... My apple tv has one hdmi, and it goes to my hd projecter.. But projecter has no speakers, and as a result I've no sound at the moment. I am looking for a clear direction to go in, to solve lack the of any sound.. My only option seems to be, using the optical out from the apple tv.. I don't have any equipment with this conecter. And I've never used optical before.. If i buy an, optical to twin phono converter and then I can plug into a large powered speaker I've got in my living room. And I will have big sound easily..?? Do I have any other reasonable options for optical enabled speakers, or AirPlay speakers or something simple I'm not aware of that will give me sound easily.. I don't want a messy 5:1 system, my house is very tidy, and I want to keep it that way. . Only having this optical out is frustrating, and I need to get my head round the options I have. Anyone understand from experience how to use the optical apple tv out. Also, not using anything but apple tv, no dvds, or tv , just apple tv and my ipad.. Is very quiet in my home right now though.

Does anyone use Optical Audio out to connect studio monitors?

I am planning to snatch a Mac Mini as my studio upgrade. I am also planning on buying some studio monitors (as opposed to just regular speakers). I was wondering what people use to get great, accurate results for under $600. The Mini can achieve optical audio out, apparently. Are there studio monitors that use digital, optical audio as a means to connect? How do fellow Logic home studio users have their audio out set up?

Scroto Saggins wrote:
well, optical is digital (right?), so wouldnt it be the only way to get the best, uncolored sound out of a Mac? what other (better) options are there? I started this topic because I dont really notice studio monitors that use optical, and I am wondering why? Whats the downside?
Because the ones that do, are way over the budget of most people on this forum.
I have this pair :

They retail at around 1500 per pair. They are not the most expensive ones out there, rather the less expensive ones with digital inputs.

Audigy 4 Pro - can only get 2 channel sound via SPDIF/optical connecti

I have two PC's, one with an Audigy 4 Pro and one with an Audigy 2 Platinum (A2P), I have my 5. speakers hooked up to the A2P and the A4P connected via the SPDIF to the A2P, I would expect to get 5. - both are setup to use 5. speakers, (I know that as a standard Digital coax/optical connections should handle multi speaker configs my entire A/V sound system (7. Dolby) uses optical and coax and it works fine).
If I run the channel test on the Audigy 4 I can get nothing but sound through the left and right speakers, if I run the test on the Audigy 2 (speakers direct connected) the sound is fine, if I reconnect the speakers to my Audigy 4 I get sound on all speakers so it looks like its an issue with the SPDIF and optical inputs (I tried both).
I have emailed tech support, I'm waiting for them to come back and tell me that the Audigy 4 cannot transmit more than two channels down the SPDIF/optical outs, thats my suspicion anyway, if that is the case then I'm not going to be a happy man and the Audigy will be going back to the store. Could be a driver problem of course as I cant believe they would implement Dolby and THX and only transmit two channels on the optical outs, that would be a bit dumb considering the primary use for digital connections is sound system interconnects.
Anyone with any ideas about this let me know, perhaps theres a hidden setting somewhere or a registry setting that switches the digital outs to carry all signals.

Just before everyone kicks off, heres a response I got from a tech guy at Creative themselves.
If you connect speakers to your sound card using a digital cable
(RCA/SPDIF or optical) then the software speaker test will only output
from two speakers. The reason for this is that the speaker test signal is
not in AC3 nor DTS format.
The signal on a digital connection is either
Optical SPDIF - which is either Stereo PCM signal or AC-3/DTS Bitstream
RCA SPDIF - which is either Stereo PCM signal or AC-3/DTS Bitstream
If you play AC3 (Dolby Digital) or DTS encoded signals, the amplifier
decodes this and outputs it to all 6 speakers (5 satellites & subwoofer)
discretely.
When playing back stereo signals (such as Wav/CD Audio or MP3/WMA files)
the amplifier may generate 5. output based on the incoming stereo PCM
signal, provided Dolby Pro Logic decoding is available and activated.
Therefore the speaker test should not be relied on when using RCA or
Optical digital connections.
This applies to all speaker systems equipped with RCA or Optical digital
connections.
This makes sense to me and I'm pretty happy with it, basically as the reply says above the speaker test does not encode to AC3 hence if you hook two Audigys together and run the test you only get 2 channel output, if you play a DVD which is AC3/DTS encoded on one Audigy and listen to speakers hooked up to the other when both Audigys are connected via SPDIF or optical you should in theory get full playback on all speakers. Hopefully

Dreamplug, 16 bit DAC, relevant when using optical out?

I am looking at this baby to use as an MPD server. The plan is to connect it to my amp through the optical out. The plan, of course, is to put Arch on it in due time (I don't know the status of the ARM port).
I assume the fact the DAC is only 16 bit does not matter when you use optical, but I just want to be sure .

.:B:. wrote:It has an SD(HC) slot as well . If I get it it'd just be running MPD, and NFS, nothing more. Should be able to squeeze that onto 1 GB (although it will probably be Debian).
Yes in that case you are probably better off putting a Slug on it instead of Arch, you'll have an mpd server up and running in no time. However, for a music station / fileserver, wouldn't an ARM NAS be an interesting alternative? They're not much bigger or more expensive, but you'll have the storage as well then.

X-Fi Xtreme Music + Digital I/O + Optical Connection for z-5

Hi there, im new and very raw so i was wondering if anyone can clear some things up.
Ive had my X-Fi Xtreme Music card for about 3 months and in that time i've been using the 3 analogue 3.5mm connections to my z-5500 controller, and i've had no problem in terms of getting full 5. sound for music and in games. Ive recently bought a digital I/O from creative to have an optical connection to the z-5500 controller.
My questions are:
1) Can i get 5. sound using the optical connection When i had the analogue connection, my z-5500 controller said it was 6. surround, but when i changed the input to optical, the controller said it was stero and not 6. surround. Ive testing the speakers in the creative console, but my rear right and rear left is mostly comming from my front right and front left speakers (something is comming out of the rear speakers but its very low)
2) Ive downloaded the dell drivers and went through the process as noted on another thread and i've successfully got the dts and dolby digital working, but how do i know it works Is there some way i can test and see if it works I mean isnt my z-5500 controller supposed to say dts or dolby digital because at the moment it isnt.
3) Is there any sound difference between an optical connection and the annalogue connection in terms of playing mp3's and games. Im aware that dts and dolby digital isnt available on the analogue connection, but i dont watch many dvd's on my comp so is there an point to have the optical connection
Thanks very much for anyone that helps.

To get a 5. spread on the 5500 with an optical or coaxial connection, you need to use the Effect button on the controller and switch to PL II Music. You can then spread the sound to the back using the Levels button and turning Surround up to your desired level. There are also some changes you can make using the Settings button.
As for the Dolby Digital and DTS, that will only show up on the controller when you are watching a DVD which supports either/or.
Hope this helps

Speakers and optical connection

Hi there,
I just got a new Mac Pro and I'm wondering if there are any audio/speaker solutions out there that allow you to use the optical out, which I assume is the cleaner, better way to connect.
Can anyone shed any light on this? Thanks.

The answer to your question about optical being noticeably better than analog is highly subjective.
IMO 98% of consumers would not notice the difference because their listening environment, the source material, and the combination of all the elements of their playback systems would combine to make it impossible to pick out the optical connection as the source for an improvement in sound quality.
Really, all that is happening is that you are depending on the D/A conversion of the speakers (logitech in this example) instead of the D/A converters built into the Mac. I would guess that both are very similar in quality, as they are both low-end consumer devices. I say that knowing that the logitechs seem expensive, and of course your MacPro is big $, but consumer devices try to do so many things that compromises are made in the pricing of the parts at the component level. They need to do this to make products that the majority of people can actually afford. In the case of the MacPro, Apple knows that the true high-end audio users (music production) are going to have commited after-market products to do their D/A conversion, so they don't need to put extra $ into the built in ones... I doubt many of the true, nose-in-the-air, audiophile types would consider a PC as an appropriate audio source when there are turntables, custom CD players that cost thousands, tube amplifiers, etc etc blah blah that only the true connoisseur would use...lol
Most consumers these days are listening to MP3s anyway, so your source material is compromised right from the beginning.
Most listening environments where a computer is being used are not optimised in order to hear that last 1-2% of "quality" difference that may or may not be linked to the cabling/connection type of the audio monitoring systems that are being used.
The real advantage you get from using the optical output is that it is the only way to get surround out of the Mac (without buying other after market gear) but your speaker system still needs to be capable of doing the decoding. Thats why the logitech system fills that niche. YMMV

Optical connection

Does anyone know if you can delay the sound output on the optical connection as it is out of sync? (when i use my av amp for the sound instead of the tv)
I can do it on my sky box, you keep adjusting the delay until the sound matches up with the speaking on the tv.
please help

No such feature on AppleTV.
This is often caused by TV video processing circuitry delaying picture output by a few msecs, which will be noticeable above a certain level to some people.
The Tv should compensate for HDMI audio, but optical/analogue from AppletV would need to be delayed by your amp if it has this option for the input.

Another user of your computer is currently using this connection. This user must disconnect before you can log on.

Hello
I have a single computer that is going to be shared between 5 people. In an effort to save time. I wanted the users to have a single shared LOCAL login to the computer.
Then each user could pull up an RDS session through RDWEB on our 2012 r2 RDS farm.
However, when I attempt to log in more than one user through RDWEB I receive:
Another user of your computer is currently using this connection. This user must disconnect before you can log on.
I have done some research on this, and followed this advice, and did the following steps on all my RDS session host and broker servers
Enable Multiple RDP Sessions
- Log into the server using Remote Desktop.
- Open the start screen (press the Windows key) and type gpedit.msc and open it
- Go to Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.
- Set Restrict Remote Desktop Services user to a single Remote Desktop Services session to Disabled.
- Double click Limit number of connections and set the RD Maximum Connections allowed to 999999.
However, it did not solve the problem. Anyone have suggestions?

Hi Michael,
In addition you can try below registry setting for multiple remote session.
HKEY_Local_Machine\SYSTEM\CurrentControlSet\Control\Terminal Server
fSingleSessionPerUser REG_DWORD 0x00000000
Note: By default the registry value is set to 1, but you need to change to 0.
Also if you are making connection through gateway then recheck whether the setting is enabled on gateway side for multiple session.
Hope it helps!
Thanks.

1     1/1/2009     0     41000027
2     1/1/2009     0     41000027
3     1/1/2009     0     41000027
I have declared an internal table as below
TYPES: BEGIN OF ty_charlist,
         line(5000) type c,
       END OF ty_charlist.
DATA: w_charlist TYPE ty_charlist,
             t_charlist TYPE TABLE OF ty_charlist.
And concatenating each field seperated by ','
CONCATENATE res1 res2 res3 res4 res5 res6 res7 res8 res9 res10 res11 res12 res13 res14 res15 res16 res17 res18 res19 res20 res21 res22 res23 res24 res25 res26 res27 res28 res29 res30 res31 res32 res33 res34 res35 res36 res37 res38 res39
INTO w_charlist-line SEPARATED BY ','.
APPEND w_charlist TO t_charlist.
Now T_CHARLIST contains 50 records which needs to be placed on other system. I can see 50 records but gap is coming
Here res1, res2 and so on are declared as TYPE STRING..
Please do help me this issue

WHEN I USED TO CONNECT INTERNET FROM MY IPHONE 4S PERSONAL HOTSPOT VIA USB, AN ICON IN THE NETWORK PREFERENCE NAMED "IPHONE" GETS OPENED.... BUT NOW THIS IS NOT HAPPENING AND I AM NOT ABLE TO CONNECCT PERSONAL HOTSPOT VIA USB CABLE. PLEASE HELP ME OUT

WHEN I USED TO CONNECT INTERNET FROM MY IPHONE 4S PERSONAL HOTSPOT VIA USB, AN ICON IN THE NETWORK PREFERENCE NAMED "IPHONE" APPEARS.... BUT NOW THIS IS NOT HAPPENING AND I AM NOT ABLE TO CONNECT PERSONAL HOTSPOT VIA USB CABLE. PLEASE HELP ME OUT???

Please don't shout! Using all uppercase means shouting on the internet. If your keyboard is stuck please say so, otherwise people will think you are being obnoxious.
Now the first question is, when you are saying connecting to personal hotspot, have you always been using the iPhone to connect to the internet? Are you someplace where the only place to connect is available via tethering to the iPhone's celluar network? Or do you have other options?

How to use JDBC Connection Pools in a standalone application?

Hi, there,
I have a question about how to use JDBC Connection Pools in an application. I know well about connection pool itself, but I am not quite sure how to keep the pool management object alive all the time to avoid being destroyed by garbage collection.
for example, at the website: http://www.developer.com/java/other/article.php/626291, there is a simple connection pool implementation. there are three classes:JDBCConnection, the application's gateway to the database; JDBCConnectionImpl, the real class/object to provide connection; and JDBCPool, the management class to manage connection pool composed by JDBCConnectionImpl. JDBCPool is designed by Singleton pattern to make sure only one instance. supposing there is only one client to use connection for many times, I guess it's ok because this client first needs instantiate JDBCPool and JDBCConnectionImpl and then will hold the reference to JDBCPool all the time. but how about many clients want to use this JDBCPool? supposing client1 finishes using JDBCPool and quits, then JDBCPool will be destroyed by garbage collection since there is no reference to it, also all the connections of JDBCConnectionImpl in this pool will be destroyed too. that means the next client needs recreate pool and connections! so my question is that if there is a way to keep pool management instance alive all the time to provide connection to any client at any time. I guess maybe I can set the pool management class as daemon thread to solve this problem, but I am not quite sure. besides, there is some other problems about daemon thread, for example, how to make sure there is only one daemon instance? how to quit it gracefully? because once the whole application quits, the daemon thread also quits by force. in that case, all the connections in the pool won't get chance to close.
I know there is another solution by JNDI if we develop servlet application. Tomcat provides an easy way to setup JNDI database pooling source that is available to JSP and Servlet. but how about a standalone application? I mean there is no JNDI service provider. it seems a good solution to combine Commons DBCP with JNID or Apache's Naming (http://jakarta.apache.org/commons/dbcp/index.html). but still, I don't know how to keep pool management instance alive all the time. once we create a JNDI enviroment or naming, if it will save in the memory automatically all the time? or we must implement it as a daemon thread?
any hint will be great apprieciated!
Sam

To my knoledge the pool management instance stays alive as long as the pool is alive. What you have to figure out is how to keep a reference to it if you need to later access it.

In the ReportDocument.Load method it tries to connect using the using the connection information embedded in the Report File

Post Author: bhaveshbusa
CA Forum: Crystal Reports
In the ReportDocument.Load method it tries to connect using the using the connection information embedded in the Report File. When the application calls ReportDocument.Load(reportFileName). This
tries to connect to the database using the connection information embedded in
the "reportFileName". This was only realised on checking the ODBC Trace
Log. The connection itself is not a problem. The problem is that the embedded
connection information is related to OLD production system. And failed
connections had raised some concerns.
Note: I am using
SetDataSource to populate the data for the report. So I don't need the
connection.
Is there any way I
can disable this auto-connect?
Thanks and

I have verified managing ports in oracle documentation, it was mentioned that if one port is busy it will try to connect to another port in the range of ports mentioned during the installtion. DBAs verified ports related file and it was blank. and they are not agreeing with this reason. Please HELP me in finding the correct REASON for this.
is it a NETWORK issue or issue with DATABASE SERVER only?
