No and no. There is an /etc/asound.conf but it starts with an '@hooks' 
and points to a pulse conf file which does not exist.

Tried both of those ideas too. No joy.

Yes, I have never before played with anything to do with asound.conf. I 
have always just installed alsa and it worked (well except for having to 
remove pulseaudio in Fedora 8 and this time in Fedora 10.

However. this got me thinking. Buried in Setup -> TVSettings-> Recording 
Profiles, there are some settings for 'Transcoders'.

The sound I get is modulated so that it could be described as 
'machine-gun'...but this is analog output from digital stream (not 
digitaloutput.)

Does anybody know what actually happens if the Sample Rateis set to 
44100 instead of 48000. Is it possible that ALL of my digital recordings 
are somehow tainted so that they will not play back properly in myth? 
The killer here is that they play nicely with mplayer....
