Thanks for the information that OSS emulation is still needed in
certain circumstances - is it for all bttv cards that need to record
audio separately? I only ask as up until now my capture cards - DVB
and PVR-350 - either encode (350) or dump (DVB) audio with the video
and as I'm running 0.16, only mythmusic needs the OSS emulation from
ALSA (AIUI). (As I have a couple WinTV cards in my spares box, I was
going to setup a slave backend with these and maybe another DVB card.)

If I was to install/upgrade to 0.18 and have no bttv cards recording
in the machine, am I able to be completely OSS free? I recall reading
that mythmusic now supports ALSA.

Good luck
