    0.27-fixes - audio just stopped

    I'm not sure if this is a result of a mythbuntu-repos update, but MythTV yesterday stopped responding to volume changes...

    At the same time, other applications have NO audio, e.g. flash, Clementine.

    I've tried messing around with settings in MythTV, but I either have no audio, or audio I can't change (whether I select PCM or Master)

    Here is the output of aplay -L

    Re: 0.27-fixes - audio just stopped

    Is anything muted running alsamixer? It would should MM instead of 00 for the volume control:

    Here is an example on how to do it and check it:

    Yeah, I checked that and nothing is muted.

    In XFCE Mixer, I have PCM and Master switches (again, not muted) but increasing or decreasing volume in MythTV doesn't move the sliders (whether I tell MythTV to control PCM or Master!)
