While debugging the sound drivers on my machine on 21 March 2011, I
came across various sources of information about the drivers. There are a total of
three sysctls of interest when debugging this sort of thing:
-
hw.snd.verbose specifies the verbosity of the output of /dev/sndstat.
When set to 0 or 1 it shows:
FreeBSD Audio Driver (newpcm: 32bit 2009061500/i386)
Installed devices:
pcm0: <HDA Realtek ALC885 PCM #0 Analog> at cad 3 nid 1 on hdac0 kld snd_hda (1p:1v/1r:1v) default
pcm1: <HDA Realtek ALC885 PCM #1 Analog> at cad 3 nid 1 on hdac0 kld snd_hda (1p:1v/1r:1v)
pcm2: <HDA Realtek ALC885 PCM #2 Digital> at cad 3 nid 1 on hdac0 kld snd_hda (1p:1v/1r:1v)
When it is set to 2, it produces much more detail, as shown below.
-
hw.snd.default_unit specifies which of the units gets mapped to /dev/dsp
and friends. It gets reset on module load, so it needs to be set after the
module is loaded and before any client opens the device.
-
debug.bootverbose is used at boot time to provide more information about the
boot process. It also works when loading modules. In the case of the sound drivers, it
produces an incredible amount of output, nearly 1000 lines. It's very
informative, but it seems inappropriate to put it in the log files:
