 Unfortunately, in my area we still use analogue tv, the switch over will
 not happen for another year or so. It's been about a month (yes, I know)
 that the channels from the analogue source play without sound. Tuning is
 (_L), but tuning is (_LMS) on the dvb (we do have 4 digital channels!!!)
 and the satellite, too.

 The info OSD on livetv (pressing i,i) shows no icon for the codec used,
 but shows stereo underneath (Arclight theme).

 Both analogue tv cards use the Saa7134 chip and the audio dev is /dev/dsp1
 for both cards (they are on two different backends).

 Older analogue recordings play fine.

 DVB, satellite and hdpvr recordings play fine (well, at the moment there
 is no picture in the sat channels but we have some very strong winds here
 so, I'm not worried yet). I don't watch much tv.

 I don't know if it's relevant, but when I open live tv, two .nuv or .mpg
 files are created, the first with zero byte length and the second is
 created after some secs, which is the one that holds the actual recording.
 I am noticing that this is regular lately. If it makes any difference, I
 checked the folders and it seems this happens when the MB has the TV card
 but the files are created on the SBE (more free space, I suppose).
