Hi, I'm still struggling with my tv tuner card.
I described the problem here: http://lists.debian.org/debian-user/2007/07/msg00340.html (ALSA problem - TV tuner no sound) The short of the long of it: sound works-- but not for the TV tuner. Chris Lane had a few good suggestions: http://lists.debian.org/debian-user/2007/07/msg00345.html My "/dev/dsp" does exist: # ls -lat /dev/dsp crw-rw---- 1 root audio 14, 3 2007-07-12 18:25 /dev/dsp Also, I tried doing what a reference in Chris' message said (see: http://people.debian.org/~terpstra/message/20070705.081707.c4fa712b.en.html ): # modprobe snd_pcm_oss # modprobe snd_mixer_oss # modprobe snd_sec_oss FATAL: Module snd_sec_oss not found. (I think "snd_sec_oss" should actually be "snd_seq_oss".) # modprobe bt878 (Then, I tried launching 'xawtv'. Sound still didn't work.) I tried unloading and reloading the bttv and bt878 modules. Nope. I played with permissions on "/dev/dsp" # chmod o=rw /dev/dsp The above didn't make a difference. I tried: $ aoss xawtv xawtv launched... no sound. I tried running xawtv as root... http://www.debian.org/doc/manuals/reference/ch-tune.en.html $ XAUTHORITY=$HOME/.Xauthority $ export XAUTHORITY $ su root # xawtv xawtv launched... no sound. As per http://www.linuxforums.org/forum/linux-desktop-x-windows/1265-xawtv-tv-my-linux-pc-picture-but-no-sound.html I installed "kdetv" # apt-get install kdetv Reading package lists...

I played with the OSS and ALSA settings: 'Settings' -> 'Configure ktdtv...' -> 'Sound' changed "ALSA Mixer Plugin" to "OSS Mixer Plugin" I changed "Volume Is Controlled Using" to "Tv card mixer" and back to "Sound card mixer". Nothing I did fixed the problem. I found a nice TV program (kdetv) in this process... but like xawtv the sound doesn't work.

How can I further trouble shoot the problem? Is there away to see that the hardware is working --beyond the tests I did before ("lspci")?
