Re: problems with snd_au8830 module under mandriva 2005

[Raymond <rayau@netvigator.com>]

When watching movie using xine (downmixing 5.1 to Surround40) with my
au8830 on 32bits machines, the 4 channels are correct at first movie
only. The Human voice (center) come out from rear speakers aftewards.

1) speaker-test -c 4 -D hw:0,0
2) using xine to play 5.1 channel-test audio samples with FFTScope enabled.

the above tests indicate that the front and rear channels are swapped
after the first play.

Please let me know if you also have this problem on your MX300.

The hardware equalizer of au8830 sound much better than the software
equalizer of XMMS.

There are follow up about how to fix 32/64bits issues related to the 
equalizer and features not presented in au8820.

alien seem have no interest to test the hardware equalizer
because of the hang oops.

This problem on STAC9704 have been fixed.
