Subject: Analog TV sound on Cinergy Hybrid T XS
Date: Mon, 02 Mar 2009 23:34:59 +0100 [thread overview]
Message-ID: <49AC5F13.7010208@codewiz.org> (raw)
Ciao,
I don't seem to be getting sound working with tvtime.
I've been trying with v4l code from 2.6.27.15, 2.6.29.rc6 and from
hg head.
devinheitmuller on #v4l suggested me to pipe the sound out from
the alsa device with
arecord -D hw:1,0 -c 2 -r 48000 -f S16_LE | aplay -
This was made a lot harder by the bloody pulseaudio, but eventually
I think I've got the right channel.
If I dump the recorded data with xxd, all I see is a fainth amount of
noise ranging from 1 to -2 (0xFEFF LE). There might be some kind of
analog mux, or a gain control?
The AC97 codec seems to be a Sigmatel STAC 9752. There's no special
casing in the em28xx code for it.
dmesg output follows:
