How can I setup sound ?

Hi Conatic,
There are some problems in using btaudio as audio player. You can check here, http://www.linuxtv.org/v4lwiki/index.php/Btaudio_(bt878). Do you have any onboard sound or dedicated sound card other than the tvtuner?

I have another card on the motherboad.

cat /proc/asound/cards

0 [I82801BAICH2 ]: ICH - Intel 82801BA-ICH2
Intel 82801BA-ICH2 with AD1885 at irq 20
1 [Bt878 ]: Bt87x - Brooktree Bt878
Brooktree Bt878 at 0xfc000000, irq 19

Is it possible to use this tvtuner card without any cable to the motherboad ?

I use

mplayer tv:// -tv driver=v4l2:norm=PAL:device=/dev/video0:alsa:adevice=hw.1,0:amode=1:audiorate=32000:forceaudio:volume=100:immediatemode=0:chanlist=eu rope-west:freq=273.25

to launch mplayer but I have no sound.

Does replacing the "hw" with "plughw" give no results?

My English is very poor, sorry
