I see. Would the manpage bit about different capabilities for SIO_REC and
SIO_PLAY modes still be of use? I know I failed to realize at first
that capabilities could be different based on how the device was opened.
Here is the log from my worst offender system:
$ export SNDIO_DEBUG=1
$ export AUDIODEVICE=rsnd/0
$ cap -p config 0
enc: s16le s24le
pchan: 2
rchan:
rate: 44100 48000 96000
$ cap -r
config 0
enc: s16le
pchan:
rchan: 2
rate: 44100 48000 96000
$ cap
AUDIO_SETPAR: Operation not supported by device
sio_getcap() failed
$ cap
/dev/audio0: Operation not supported by device
sio_open() failed
$ cap
/dev/audio0: Operation not supported by device
sio_open() failed
$ cap -p
config 0
enc: s16le s24le
pchan: 2
rchan:
rate: 44100 48000 96000
$ cap
/dev/audio0: Operation not supported by device
sio_open() failed
$ cap
AUDIO_SETPAR: Operation not supported by device
sio_getcap() failed
On this system, after sio_getcap fails for the first time, any further
sio_getpar and get_getcap requests become unreliable/inconsistent and
occasionally completely lock-up the sound subsystem, so the device cannot
be opened at all - have to reboot at this point. Opening the device
only in SIO_PLAY or SIO_REC mode sometimes sort-of resets it (as you can see
in the log above). Also get this on console for every failed sio_getcap:

Second system with the same symptoms, but without noticed
hard lock-ups yet (running "cap -p" or "cap -r" seems to reset it):
$ cap
/dev/audio0: Operation not supported by device
sio_open() failed
$ cap -r
