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?

Hello,
I am having an issue with my playback application where upon playback start, only the left speaker is outputted. But if I mute and unmute (either through my application or using alsamixer), the sound playback resumes on both left and right speakers. This only happens on a particular system too (out of 5 systems). But I know it is my issue because mplayer or smplayer works fine.
I believe I am setting the correct HW params (ie. 2 channels), etc.
Any ideas?
Thanks!
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.
