[mythtv-users] Surround Sound Processing in Linux

[lists at higgers.me.uk]

Hi All,

I have recently been working on getting mythtv to output sound via Jack.  I have
successfully got sound routed from Myhtv (and Amarok) into Jack and from there
to my soundcard.  My long term aim is to do all sound processing on the
frontend box and remove the need for a surround sound processor.  This will
allow me to perform digital room correction on the frontend box and not have to
spend a fortune on an AV processor that can do DRC.

However, I have no idea if it's possible to put a surround sound decoder
somewhere along the path from MythTV to the soundcard.  At the moment I can
only listen to stereo sound from my recordings unless I engage the surround
sound processing in my AV processor.  Is there a plugin I can use in MythTV or
Jack that will do Dolby Surround decoding?

Decoding Dolby/DTS 5.1 seems to be a different matter.  I've read that Xine and
MPlayer can decode a 5.1 stream and route it to the sound card.  I haven't
tried this personally yet, I'm concentrating on TV viewing at the moment.

My recordings are all via DVB-T in the UK and don't contain any 5.1 audio
streams, just plain stereo.

Thanks in advance,

Steve.
