Is there a simple "how to" guide for getting sound to work with FreeBSD? The handbook seems to concentrate on playing MP3 files and ripping CDs. I suppose I'd better start from the beginning... FreeBSD 4.10-BETA, Acer MX3-W Pro m/board. dmesg | grep pcm: pcm0: <Intel ICH (82801AA)> port 0xdc00-0xdc3f,0xd800-0xd8ff irq 9 at device 31.5 on pci0 pcm0: <Analog Devices AD1881 AC97 Codec> cat /dev/sndstat: FreeBSD Audio Driver (newpcm) Installed devices: pcm0: <Intel ICH (82801AA)> at io 0xd800, 0xdc00 irq 9 bufsz 16384 (1p/1r/0v channels duplex) mixer: Mixer vol is currently set to 75:75 Mixer pcm is currently set to 75:75 Mixer speaker is currently set to 75:75 Mixer line is currently set to 75:75 Mixer mic is currently set to 75:75 Mixer cd is currently set to 75:75 Mixer rec is currently set to 75:75 Mixer line1 is currently set to 75:75 Mixer phin is currently set to 0:0 Mixer phout is currently set to 0:0 Mixer video is currently set to 75:75 The sound works just fine when playing CDs or MP3 files, but how does one record? Not knowing any better, I plugged the audio source into the mic input, and just did a "cat /dev/audio". What I seemed to end up with was a raw .AU file, which few programs can recognise (I tried SoX and Audacity). If I copy it back to /dev/audio, I hear the original, but I have a feeling that I'm missing something. So, is there a "better" way? I'd be looking to produce MP3 or WAV. -- Dave
