Re: [alsa-devel] [Jackit-devel] position_fix issue snd-hda-intel (was jack issue)

Donnerstag, 7. Februar 2008 Stephane THOMAS:

I found position_fix=3 works for the chip I have (ALC888).

I confirm that with this parameter passed to the module, jack works fine. But using ALSA directly produce (? samplerate mismatch).

Just to sum it up:

For, at least, our two snd-hda-intel devices (ALC888 and 82801I (ICH9 Family)) both position_fix values (POSBUF and FIFO, 0 and 3 respectively) produce ok sound, only that

position_fix=0 makes alsa fine and jack crackle/sizzle position_fix=3 makes alsa crackle/sizzle and jack fine

"alsa" meaning direct use of alsa and "jack" meaning (at least in my case) jack with the alsa backend.

Here I have alsa-1.0.14-31.2 and jack-0.109.2-0.pm.1 (0.pm.1 stems from the packman repository, I guess)
