</div></div>Just a couple points to note:<br>
<br>
1) internal volume control does not work with passthrough (and<br>
cannot work with passthrough without softvol hacks or similar).<br>
2) if you're outputting multi-channel audio or "non-standard"<br>
outputs in ALSA (Line, Headphone, any surround channel, etc.--basically<br>
anything but PCM or Master), changing the master volume control will<br>
have no effect with most ALSA drivers (and changing PCM volume control<br>
will also, as expected, have no effect).<br>
<br>
Both are sound driver/sound system "features" and have nothing to do<br>
with Myth.<br>
<br>
</blockquote></div><br>I know my way around Linux pretty good but I haven't really messed with any of the audio stuff, so this is new territory for me. I don't know what passthrough is. I gather that has something to do with passing audio from the line-in jack to the output? I am not doing anything special. I am just playing back SD mpeg from a PVR-150. The sound volume controls work fine outside of Myth. Also I am using Intel integrated audio on my BE/FE fine. I assume there is some setting that I need to adjust to let Myth know how to control the volume on my system. Any help would be greatly appreciated.<br>
