[lug] Popping in i810_audio

[Bonnell, Doug]

This URL doesn't pertain to the i810 audio per se, but
it does mention that the "pop" is caused by the driver
doing a "calibration".

Hope this points in the right direction for you.

Hello,

  I've got a new HP Pavilion with an i810 board and i810 audio.
I've got a bad "pop" that occurs whenever audio begins to play.
This happens with "play" and xmms although it seems to be better
if xmms uses the aRts Driver rather than OSS or esd.  I'm guessing
that the aRtsd code ramps up volume to hide the pop.

  Anyone familar with this problem?  Is it caused by the i810_audio
driver ( I've tried the driver with 2.4.8 and it still occurs ).
Is the 'Alan Cox' who's credited with writing the driver the same
Alan Cox of kernel fame?  Kernel Changelogs are not particularly
useful for determining if the issue has ever been addressed.

Thanks,

Scott
