<br><br> I think have tried every possible volume slider in alsa mixer and none make a difference. I do this while I have something playing to make it easier to hear a difference. Myth's internal volume controls are disabled as well. I solved my audio dropouts on AC3 material, seemed to be a conflict with XvMC, which I have shut off for now and went back to libmpeg2 for playback for now which seems to work smoothly.
<br><br>Thanks for the suggestions. Is there a specific volume slider I should check. Although I believe I have slid them all to varying points with no change to my stereo audio. AC3/DTS works as it should with proper output.
