alsa+audigy ls=no sound

I recently bought a CMI8738 sound card and the audio output was just awful, so I eventually threw up my hands and upgraded to the Audigy SE (Audigy LS in lspci)... now I have NO sound. I've read dozens of threads on LQ regarding woes with alsa and no sound with the LS, but none seemed to offer a clear solution. I've run alsaconf multiple times. I installed all available alsa drivers (--with-cards=all) and alsaconf detects what I've confirmed to be the correct driver for my card, ca0106). It loads all the necessary modules just fine. I have tested this with a live cd (Ubuntu in this case) as well with no different results.

I'm just going to do a data dump (might be a little overkill)...

Dumb question, but have you 'unmuted' the card? Alsa drivers are muted by default. You can fix it by running alsamixer.

Alsamixer shows all channels as muted while alsamixergui and my volume control gnome-applet shows everything excluding Line In, Phone and Aux as unmuted by default. The reason for this, as I just discovered, is due to the fact alsamixer only displays these IEC958 channels. In alsamixer, line in and mic are combined and cannot be adjusted. I can turn up everything and still be without sound. Also, it seems a bit odd that the chipset is not displayed in the alsa mixers.

Thanks for the suggestion, but I'm all set in that area.

I've been reading around some more and the situation is looking pretty grim (ie: time to buy yet another sound card). If alsa's site wasn't always down I might be able to get some more information, but I guess not.

If anyone else has this same problem, let me just say it doesn't look too good. It sounds like you might get better results if you use OSS. As of alsa 1.0.11, it doesn't seem the SB0570 variant of this card is supported.

This external thread is identical to the bind I'm stuck in.

The most discouraging comment I've seen can be found in the above posting.
"The CA106 based cards are one of those that are to sound, what a winmodem is to a real modem."

I spent I don't know how many hours trying to get my old winmodem to work and I was never able to pin it down.

"You bought based on price, always a chancy thing to do for a linux system. One really should check the hardware compatibility lists before
quoting card numbers over the phone.

I too have an audigy, but its a 2 Value, and does all that in onboard hardware. I would recommend you return that one to newegg, and get a hardware based card such as an audigy 2. You'll be 1000% happier with the results."

If anyone's gotten this variant of card to work with alsa, I'd be happy to know how it was accomplished.

Creative Labs cards have poor sound quality even their X-Fi which is not yet supported. I recommend Audiotrak Prodigy 7.1LT or Terratec Aureon Space 7.1. These two sound cards are based on VIA 1724HT DSP chip which provides better sound quality than the X-Fi at a fraction of the cost. I have Audiotrak Prodigy 7.1 and its sound quality equals professional sound cards like the Lynx Studio Technology LynxTwo. Unfortunately, these two sound cards are out of stock in most stores that carry it and they need a software mixer to help them handle more than one sound stream.

I never resolved what I'm assuming to be driver incompatibilities with this variant of card. I was able to salvage a Aureal Vortex 1 sound card from an old computer and it is working great. It's even able to play multiple sound streams simultaneously, which I wasn't able to get working on my old integrated i810 audio chip (although I never tried).

I appreciate the suggestion though, Electro. You made the same recommendation in my other thread (here). I actually found this card on ebay but it's a little too expensive and- how shall I say- fancy, for my needs. I don't need anything all that impressive. The only reason I need an audio solution is for videos.

The sound cards that I suggest are not fancy but produces high quality sound. The advertised features like hard wire is not even used in Linux because there is no professional formats other than jack. Jack can be used with the ALSA. Creative Labs sound cards are more fancy than the cards that I suggest because they have all the bells and whistles that do not produce high quality sound.

On-board sound like from the Intel needs a software mixer. ALSA has this as a library called dmix. A dmix configuration is not compatible with many programs.
