>Description:
newpcm driver doesn't realize that an old process doesn't exist
anymore and I thus can't use it anymore:
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Intel ICH6 (82801FB)> at io 0xf4001000, 0xf4002000 irq 17 bufsz 16384 kld snd_ich (1p/1r/0v channels duplex default)
[pcm0:play:0]: spd 22050/48000, fmt 0x00000020/0x10000010, flags 0x00001030, 0x00000010, pid 9704
interrupts 164390, underruns 164361, ready 0
{userland} -> feeder_root(0x00000020) -> feeder_monotostereo16(0x00000020 -> 0x10000020) -> feeder_endian(0x10000020 -> 0x10000010) -> feeder_rate(22050 -> 48000) -> {hardware}
[pcm0:record:0]: spd 0, fmt 0x00000000/0x00000008, flags 0x00000000, 0x00000000
interrupts 0, overruns 0, hfree 16384, sfree 0
{hardware} -> feeder_root(0x00000000) -> {userland}
No messages in /var/log/messages.
>How-To-Repeat:
I think it happened when net-im/gaim received a message while
multimedia/xmms was just starting up, but haven't been able to
reproduce it up to now.
