I can't seem to get any audio output from the analogue jacks on the Chaintech AV-710 soundcard.
My current setup is:
Athlon 1800+ with Coolermaster Vortec Dream 7 HSF
MSI K7N2GM2-LSR
Samsung 512mb PC3200
WD 200gig HD
AV-710 soundcard
Hauppauge PVR-250 capture card
Coolermaster Cavalier 2 case (the one with the sound meter built into the front)
I using the supplied s-video bracket for the tv out from the mobo with the integrated graphics onboard (nVidia)... onboard sound is disabled, of course.
Everything works well and I have sound working via the sp/dif output from the chaintech card but I can't get any sound from the analogue outs.
I've installed the latest ALSA drivers... 1.0.9rc2
I've followed everything I can find online with regard to setting up ALSA but still no luck. Also, last night I tried playing TuxRacer after exiting the MythTV frontend and there is no sound just in Linux either. I've checked that Master, PCM, and Headphones are not muted in Alsamixer... I'm out of ideas.
Did I mention I'm a total Linux noob that hadn't looked at linux before a month ago? I know that doesn't help but that's why I think I may have missed something basic... a lot of people seem to have more trouble getting sp/dif to work than analogue and I've got the opposite problem... doesn't make sense and that's what leads me to think I'm missing something that a Linux expert wouldn't even think to mention.
I've found some information in other forums like AVS Forum that pointed to "make sure your "IEC958 Output Switch" is not muted in alsamixer" which I did look at but I can't seem to move the volume level up on IEC958 0 and there is two settings on either side of it that are labled IEC958 and IEC958 1 that have PCM Out above them without the volume slider graphic... I have no idea what changing these does other than causing the sp/dif out to stop working all together.
Also, last thing... I tried moving the audio out jack on the sound card from Line Out to Center/Bass to Surround Out to ALT Out... and everything was completely quiet except for ALT Out (that's the jack next to the SP/DIF out)... which was filled with very loud static-like white noise (? if that's the correct term).
Sorry for the long post but and I know it sounds a strange request when I have the audio working fine through the superior connection but I would like to be able to just watch the MythTV feed on my TV without having to power on my main sound system... it's just too inconvenient for my wife. That's the deal breaker in this... if she isn't happy, I'm not happy. All married guys know what I mean

No takers for a possible solution to this particular problem.... so I'll ask something else. Does anyone have any suggestions where I might be able to find to particular solution to this problem for a person fairly new to Linux. I have no trouble reading a bunch and I've already learned quite a bit about Linux since I took this project on.... if someone can recommend sites (I've been to quite a few Linux noob sites already but they don't seem to delve into trouble shooting drivers and such) or even a book or two worth purchasing for someone of my skill level would be greatly appreciated.
TIA...

I don't know about other people, but my problem is I have never heard of an AV710 soundcard.

I can post some links to the product and some links to other forums that recommended it for a linux setup... wasn't sure if that was frowned upon or not.
Chaintech 7.1 Channel PCI Sound Card
General Features:
VT1721 ENVY24 HT-S Chipset
New Multi-channel sound chip
PCI 2.2 I/F with bus mastering and burst modes
7.1 Channel Speaker support
Compatible with SB16 (Sound Blaster)
24-bit resolution audio format support
Sampling rates up to 192KHz
Supports Mic In / Line In / 4 Line outs & Digital
Optical output

It was a great deal at less than $20 Cdn. and came with a 6ft toslink cable in the box as well.

I don't think you can do both simultaneously. I've had a couple 5.1/7.1 cards including the ever poplar Live 5.1. You can chose between SP/DIF and Analog, but not BOTH, regardless of OS (Windoze, Linux etc).

Okay... there was a post in another forum (Head-Fi http://tinyurl.com/3qfc7 )
"In order to get the Chaintech AV-710 to run in high-res mode and use the superior Wolfson DAC, download the asound.state file (available below). Copy this to your /etc/ directory as root, and run ‘alsactl restore’. This will enable the high-resolution jack. Notice that this will not mute the volume on your speaker outputs (unlike the windows version), so you can listen to your headphones and speakers at the same time. It’s a fun effect, but you’ll probably want to disable it. To do this, open up alsamixer and mute the ‘Master’ and ‘Master Mono’ controls. If you want your speakers muted by default, then after alsamixer run ‘alsactl store’."
The above quote was at the bottom of a long setup guide, mostly aimed at windows users, with a paragraph dedicated to Linux at the end. I did follow these instructions without the end part about muting 'Master' and 'Master Mono' and then running 'alsactl store'.
I have a very specific need for this as I'd like to be able to run the analogue audio to my tv and the sp/dif to my surround system and not have to disable/enable a setting to listen to either... other than muting the tv, of course. This will simplify things greatly for my wife and make the system uber-usable... keeping her happy... keeping me happy.
If there is a flaw in the above instructions I've pasted from the Head-Fi forum please let me know... or anything else you can think of for me to try.
Thanks,
|

I snooped throught the post, 2 things:
1] When they say High Res mode and DAC, "High Res" = S/PDIF Digital Out? I noticed they call it high-resolution jack, which is not a JACK ... anyways very poorly written directions!
2] It may not work for you beacause of conflicting versions of ALSA and possibily the card's firmware (too recent maybe). The alsa.state may have been saved by an older version of alsactl (even thou once you manipulate the volumes using alsamixer, it should update their status regardless)
You might have to find another solution. Run an RCA cable from your Receiver to your TV  . Yeah .. it'll have to be on, but it might just be simpler hehe![/list][/list]

I have a feeling the solution to this one is well beyond me and I was hoping that the fix was simple... I may need to put a lot more time into understanding linux and that means that I "might" solve this one so far down the road that my equipment will have gone through a upgrade cycle or two which may solve the problem for me. Oh well... the reason I can't go from the receiver to the tv is because my surround system consists of a set of Logitch Z-5500s... I could run the "ipod" output on the side of the control module to the tv but then the surround system has to be turned on for output to the tv... if that's the case I'll just listen to the speakers. I was hoping to avoid my wife having to turn on the speakers at all. If there's too many steps to watching the PVR my wife just won't use it.

Yeah ... I feel your pain, it has to be wife-proof  .
You might want to experience with multiple configurations:
1] Swap the card out and try different PC
2] Fresh full install using Fedora (e.g.) - popular guide at: http://wilsonet.com/mythtv/ (a little time consuming, not sure if its worth your time)
3] Add a 2nd sound card, not sure how easy it is to use both cards
4] Download, compile ALSA
Or .. you could maybe just use Analog over to the Logitech system, and then its easy .. just splice the connection to your TV.

Yeah... I thought about the last point but I'm not sure I can get any output from the analogue outs on the chaintech soundcard... the only thing that's ever worked (I've installed the last 3 versions of KnoppMyth fresh) is the sp/dif out.
I've had some help in another forum as well and if I do get this sorted I'll be sure to post the solution.

Can you post a link to the other forum/topic?

Sure...
http://tinyurl.com/5ln59
that should get you to the topic... most of what we covered here except a user in that forum has had an experience similar to mine with this exact card and Linux and he's helping with what worked for him.
This is the forum I was reading when I made the decision to go with this card as it was so highly recommended as best bang for the buck audio wise and a lot of people were actually using it. There's some interesting reading there... if you're into that kind of stuff. I found it to be leaning to high-end audio sensibilities but not that wine-tasting, snooty terminology, high end.
