[alsa-devel] Alsa Issue - Sound playback starts on left speaker only

[Ashwin.Chandra at corel.com]

I have an Intel ALC861VD. Other players (mplayer, smplayer, aplay) don't
seem to exhibit this problem. Is there any workaround I can do in my
application so that upon first time sound playback, I can get it to play
on both channels?

The ICE1724 driver has exactly this behavior.  It is a known bug and has

been there for years.
You don't say what chip is having the problem, but I would guess that 
this is it.  Most people
just program a script to adjust the volume at startup to cure it.
