[alsa-devel] snd_hda_intel error

I am using the driver from the 2.6.31.1 kernel
I neglected to include this line from dmesg
hda-intel: IRQ timing workaround is activated for card #1. Suggest a bigger bdl_pos_adj.
I don''t know if that is related or not.

No it's not. I provided a fix for this bug in alsa-lib. http://git.alsa-project.org/?p=alsa-lib.git;a=commit;h=aba87e509898ec9ddb3e3... You can implement a work-around by using hardware devices in your mixer profile instead of front: -Pierre

You'll at least want to try a daily snapshot, ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.bz2, and use http://www.alsa-project.org/alsa-info.sh.

Sorry, that was a typo. It should be 2.6.36.1

Which application is recording ?
Please provide a test case which can reproduce the problem ? (with a full pulseaudio log )
