Did anyone ever find a solution for those onboard sound chips like
sis7012/cmedia 9739 etc. that are treated by i810_audio as having one fixed
sample rate of 48 khz? These chips produce chipmunk sound e.g. when you
play a sound in a rdesktop session (wts gives you 44.1 khz played back
with 48 khz).
Google tells me that many linux users complain about this issue, but I
never found a solution. CMedia says the 9739 has variable
sampling rate up to 96 khz, and the windows driver gives me a whole
bunch of rates. But i810_audio says "id: CMI131 (unknown)". When I try
to alter the sampling rate (e.g. option i810_audio clocking=44100 in
modules.conf) the driver prints out "only 48khz playback available",
that's it. Adding sound-esd or sound-nasd packages was useless for me.
Maybe a newer i810_audio is available that recognizes actual cmedia
codecs correctly? Or can we have the cmedia driver (version 041 from
their website) available as a thinstation package? Or is there a way to
redirect rdesktop sound output through sox to get resampled sound? Or
anything else? I am too much a newbie to this sound thing.
Unfortunately I must say that I am one of these poor users with a
windows-only environment. I am therefore very very thankful for
ts-o-matic, what is the most fantastic help for us I have ever seen.
