Subject: Recording problem on cs46xx on recent linux kernels
Date: Fri, 10 Dec 2004 14:59:55 +0100 [thread overview]
Message-ID: <1102687196.10057.15.camel@localhost> (raw)
Hi,
since moving from kernel 2.6.9 to 2.6.10-rc2 and -rc2-bk4, I was happy
to see that hardware mixing is now supported on my hardware
(CrystalClear SoundFusion Audio Accelerator on a IBM T22). However I
have also been experiencing a new problem when recording from the
soundcard: a readi returns -5 after about 5 seconds, with parameters
that used to work. I'm using libalsa v1.0.7 (Debian unstable) and Linux
2.6.10-rc2-bk4 with cs46xx and "New DSP support".
The /proc says that the capture PCM is running, but the available field
remains to 0.
