I put a whole ton of lines into my modprobe.conf without really affecting anything. One thing I learned is that with snd_bt87x, the alsa recording of the tv sound works fine: arecord -D hw:1,1 -f S16_LE -t wav test.wav However, the sox recording of the dsp doesn't make any noise but a slight hiss: sox -w -r 32000 -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp So I think its a modprobe.conf issue or a snd_pcm_oss kind of issue. Basically if ALSA:1,1 works, but /dev/dsp1 doesn't, its probably an ALSA-oss translation issue, right? I changed modprobe.conf around and cut part into modprobe.d/tv. For some reason snd_bt87x module doesn't load on boot anymore. I don't understand modprobe or udev or how modules are loaded very well. This is my new modprobe.d/tv file: alias char-major-81 bttv options char-major-81 card=63 gbuffers=4 automute=0 tuner=2 alias tuner0 tuner # ALSA portion alias char-major-116 snd alias snd-card-1 snd-bt87x options snd-card-1 index=1 load_all=1 # module options should go here # OSS/Free portion alias char-major-14 soundcore # card #1 # OSS/Free portion - card #1 alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss # OSS/Free portion - card #2 (cmipci) alias sound-slot-1 snd-card-1 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-3 snd-pcm-oss alias sound-service-1-12 snd-pcm-oss #alias sound-slot-1 snd-bt87x #alias sound-service-1-0 snd-bt87x #alias sound-slot-2 btaudio #alias sound-service-2-0 btaudio -Eric Hattemer ------------------------------------------------------------------------- Using Tomcat but need to do more?
