If you run mythfrontend 0.22 from RPMfusion, it will automatically try to disable pulseaudio and use the default ALSA output instead. This leads (in most cases) to no audio output at all.

Changing mythtv’s audio output device in the frontend (Utilities/Setup -> Setup -> General -> Audio System -> Audio Output Device) from ‘ALSA:default’ to ‘ALSA:spdif’ worked for me, but then the volume control (internal as well as external) was broken.

But you can easily tell mythtv to stop disabling pulseaudio by setting EXPERIMENTALLY_ALLOW_PULSE_AUDIO=1 in your environment before running mythfrontend.

For example, add an export statement to your .bashrc

echo "export EXPERIMENTALLY_ALLOW_PULSE_AUDIO=1" >> ~/.bashrc

(Of course, if you use another shell, YMMV!)

Set mythtv’s default audio output device to ‘ALSA:default’ and the volume control to Master (instead of PCM) and voilà, sound!

Remote controls for PCs are really great. With an ordinary remote for just a few bucks you can control almost everything on your PC while sitting on your couch. Well, thanks to lirc, of course. But most of them have one major design flaw: They’re infrared based, i.e. remote controls transmit data on an modulated infrared beam to your IR-receiver. Even a (think) sheet of paper can block the beam. So your remote always has to be within visual range of your receiver.

But there are some remotes out there which use a 433MHz beam instead of the short-waved IR-beam. For example this one by X10
