Subject: i810 audio problem
Date: Mon, 18 Jun 2001 14:17:15 +0200 [thread overview]
Message-ID: <20010618141715.A534@argo.tin.it> (raw)
Switching from 2.4.2 to 2.4.5 breaks i810_audio on my intel MX440 based notebook:
After some (in fact a few) seconds of playback it gets stuck until the app closes and reopens /dev/dsp. (I do NOT use esd)
I tried 2.4.4 and 2.4.5 (and the ac patches on both) but it does't work anyway.

It goes on until I kill the app, then it says:
Jun 18 13:59:42 argo kernel: i810_audio: drain_dac, dma timeout?
Any idea(s), suggestions ...
Thank you
