<pre>Here is my OSS configuration on FreeBSD:
$ cat /dev/sndstat
Installed devices:
pcm0: <NVIDIA (0x0044) (HDMI/DP 8ch)> (play)
pcm1: <NVIDIA (0x0044) (HDMI/DP 8ch)> (play)
pcm2: <NVIDIA (0x0044) (HDMI/DP 8ch)> (play)
pcm3: <NVIDIA (0x0044) (HDMI/DP 8ch)> (play)
pcm4: <Realtek ALC892 (Rear Analog 7.1/2.0)> (play/rec) default
pcm5: <Realtek ALC892 (Front Analog)> (play/rec)
pcm6: <Realtek ALC892 (Rear Digital)> (play)
pcm7: <Realtek ALC892 (Onboard Digital)> (play)
pcm8: <USB audio> (rec)
PulseAudio doesn't detect any devices after the pcm4 line.
This is because that line is exactly one character too long for the
line[64] buffer in detect_oss(). The newline character from that line
is read in during the next iteration, which detect_oss() interprets as
an empty line that ends the "Installed devices" section.
Note that lines in /dev/sndstat can be significantly longer. On FreeBSD
setting sysctl hw.snd.verbose adds debugging information with lines up
to 109 characters on my system. I suggest increasing the buffer size to
at least 256.</pre>
