Patrick,
Hi. Ok, since you suggested it I set up this Via 8235 sound chip on
my system as the primary sound chip. However, it's sounding amazingly
bad! It's terribly distorted and even at the best of times sounds very,
very,phasey. I can pretty much hear what sound like terrible resampling
noise, maybe like it's going from 44.1K up to 48K or something.
Any idea why? I hope it's just a configuration mistake.
I've tried both alsaplayer and xmms playing a few mp3's and the results
are always the same going through the 8235.
The 8235 output is cabled to an input on the AI-3 A/D, inputs 3/4. I've
also got Pro Tools coming in on inputs 1/2. Audio from Pro Tools is
fine, while audio from the 8235 is dirty, resampled and phasey. The AI-3
does not show any clipping on the signal coming from the 8235, so I
don't think it's really a levels issue.
Is the 8235 a 44.1K only type device? I don't think so since I see 44.1K
number in /proc/asound/card0/
I haven't figured out how to run alsaplayer directly though Alsa when
the HDSP is the second card, but using Jack I can run alsaplayer and the
sound is much better.
I think there have been similar comments since rc1 about this sort of
thing on the Intel sound chips possibly? Are others using rc2
successfully with this chip or could this be a similar problem?
The sound is so bad as to be unlistenable.
Current .asoundrc and modules.conf below...
Thanks,
Mark
