I'm having problems trying to record from a sound card under 8.1-RELEASE. The last time I tried this was many releases ago=2C possibly 4.x-RELEASE. Back then I would do something like "cat /dev/dsp > file" but now when I try it I just end up with a 0 byte file. I'm using a different sound card than before so maybe that has something to do with it. Or possibly I just don't know which device to use. Playing sounds using "cat file.wav > /dev/dsp0.0" works fine=2C but I can't get recording to work. Does anyone have any suggestions? Thanks. $ cat /dev/sndstat FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386) Installed devices: pcm0: <Creative CT5880-C> (play/rec) default $ sysctl -a | egrep '(snd|pcm|sound)' hw.snd.vpc_reset: 0 hw.snd.vpc_0db: 45 hw.snd.vpc_autoreset: 1 hw.snd.latency_profile: 1 hw.snd.latency: 5 hw.snd.report_soft_matrix: 1 hw.snd.report_soft_formats: 1 hw.snd.compat_linux_mmap: 0 hw.snd.feeder_eq_exact_rate: 0 hw.snd.feeder_eq_presets: PEQ:16000=2C0.2500=2C62=2C0.2500:-9=2C9=2C1.0:441= 00=2C48000=2C88200=2C96000=2C176400=2C192000 hw.snd.feeder_rate_quality: 1 hw.snd.feeder_rate_round: 25 hw.snd.feeder_rate_max: 2016000 hw.snd.feeder_rate_min: 1 hw.snd.feeder_rate_polyphase_max: 183040 hw.snd.feeder_rate_presets: 100:8:0.85 100:36:0.92 100:164:0.97 hw.snd.vpc_mixer_bypass: 1 hw.snd.verbose: 0 hw.snd.maxautovchans: 16 hw.snd.default_unit: 0 hw.snd.version: 2009061500/i386 hw.snd.default_auto: 0 dev.pcm.0.%desc: Creative CT5880-C dev.pcm.0.%driver: pcm dev.pcm.0.%location: slot=3D9 function=3D0 dev.pcm.0.%pnpinfo: vendor=3D0x1274 device=3D0x5880 subvendor=3D0x1274 subd= evice=3D0x2003 class=3D0x040100 dev.pcm.0.%parent: pci0 dev.pcm.0.eapd: 1 dev.pcm.0.play.vchans: 1 dev.pcm.0.play.vchanmode: fixed dev.pcm.0.play.vchanrate: 48000 dev.pcm.0.play.vchanformat: s16le:2.0 dev.pcm.0.rec.vchans: 1 dev.pcm.0.rec.vchanmode: fixed dev.pcm.0.rec.vchanrate: 48000 dev.pcm.0.rec.vchanformat: s16le:2.0 dev.pcm.0.buffersize: 4096 dev.pcm.0.bitperfect: 0 dev.pcm.0.spdif_enabled: 0 dev.pcm.0.latency_timer: 32 dev.pcm.0.polling: 0 $ 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 73:73 Mixer cd is currently set to 75:75 Mixer rec is currently set to 75:75 Mixer igain is currently set to 0:0 Mixer ogain is currently set to 50:50 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 Recording source: mic =
