I have already done that settings. I'm sorry to write that.
And it's no problem when I don't use PVR-350 tv-out.

But Using PVR-350 tv-out, MythTV seems not to be able to control just L/R mute mode.
It's more than probable that MythTV doesn't use /dev/mixer to ontrol just L/R mute mode.
When it's muting both left and right, it use /dev/mixer.

Since PVR-350 sound-out is connected to sound card's line-in,
MythTV can't control just L/R mute without /dev/mixer.

Thanks
