The Chaintech AV-710 soundcard is a 7.1 soundcard which uses this driver. It has two DACs. There's a standard DAC that drives the first six channels. The rear surround channels, however, are driven by a high-quality Wolfson DAC. Audio enthusiasts like to set the card to drive the main two channels through this DAC instead in order to get a very high quality stereo line-level output. The card's Windows driver has an option to do just this, and in the past people have been successful doing it on Linux. I am attaching an asound.state file which owners of this card used with ALSA 1.0.7 to achieve this. However, I am having trouble getting this to work with ALSA 1.0.8. The rear surround output just produces white noise all the time. This is the case both with this asound.state loaded and also with default levels (i.e., what I get if I wipe /etc/asound.state and re-run alsaconf). It'd be nice to know what changed between 1.0.7 and 1.0.8 that caused this to break, and how to fix it. Thanks! ====================================================================== ---------------------------------------------------------------------- jaanusk_ - 05-09-05 10:43 ---------------------------------------------------------------------- Interesting, the originally attached asound.state is working ok for me. AdamW: did I understand correctly that after applying the attached asound.state you get no sound nor noise when trying to play back audio? ---------------------------------------------------------------------- AdamW - 05-09-05 18:09 ---------------------------------------------------------------------- Actually, now it's OK, I just had to use the asound.state from this thread but delete control 7 from it (ALSA kept complaining about it, probably because I compiled driver 1.0.8 but I still have libs and tools 1.0.9rc). Now it works fine :). As soon as this patch is merged, I consider it fixed. Thanks a lot! Mmm...Wolfson...
