Hi all, Just been testing a known working microfone in my Asus P4800E-based box, with various recording programs, with no luck. It just seems dead. The microfone device is actually alive hardware-wise, as there is a windows partition on this box, and that works. pcm0: <Intel ICH5 (82801EB)> port 0xee80-0xeebf,0xe800-0xe8ff mem 0xfebfb400-0xfebfb4ff,0xfebfb800-0xfebfb9ff irq 17 at device 31.5 on pci0 pcm0: [GIANT-LOCKED] pcm0: <Analog Devices AD1985 AC97 Codec> 'mixer' settings are fine, (rec,mic,etc..) all at ~75, and recording source is 'mic'. I have two inputs, line-in and mic, and i've tried both (obviously setting 'line' to a ~75 mark, too.) I've checked some archives, and a few others with similar setups have this problem. I found one with a mention of a patch, of which i added the diffed code to ac97.c to take advantage of the mentioned 20dB gain increase, but still no luck .. (that thread: http://lists.freebsd.org/pipermail/freebsd-multimedia/2003-July/000357.html) Here is some sndstat debug at verbose=2: FreeBSD Audio Driver (newpcm) Installed devices: pcm0: <Intel ICH5 (82801EB)> at io 0xfebfb800, 0xfebfb400 irq 17 bufsz 16384 (1p/1r/4v channels duplex default) [pcm0:play:0]: spd 44100, fmt 0x10000010, flags 0x00001020, 0x00000000 interrupts 31849, underruns 11865, ready 0 {userland} -> feeder_vchan_s16(0x10000010) -> {hardware} [pcm0:record:0]: spd 44100, fmt 0x10000010, flags 0x00000000, 0x00000000 interrupts 0, overruns 0, hfree 16384, sfree 131072 {hardware} -> feeder_root(0x10000010) -> {userland} pcm0:play:0[pcm0:virtual:0]: spd 44100, fmt 0x10000010, flags 0x10003030, 0x00000000, pid 1965 interrupts 0, underruns 0, ready 131072 {userland} -> feeder_root(0x10000010) -> {hardware} pcm0:play:0[pcm0:virtual:1]: spd 0, fmt 0x00000000/0x00000008, flags 0x10000000, 0x00000000 interrupts 0, underruns 0, ready 0 {userland} -> feeder_root(0x00000000) -> {hardware} pcm0:play:0[pcm0:virtual:2]: spd 0, fmt 0x00000000/0x00000008, flags 0x10000000, 0x00000000 interrupts 0, underruns 0, ready 0 {userland} -> feeder_root(0x00000000) -> {hardware} pcm0:play:0[pcm0:virtual:3]: spd 0, fmt 0x00000000/0x00000008, flags 0x10000000, 0x00000000 interrupts 0, underruns 0, ready 0 {userland} -> feeder_root(0x00000000) -> {hardware} Your's stumped!
