hello,
since the commit:
42fdcd9fd917 snd_uaudio(4): Fix config detection with defaults set.
my snd_uaudio(4) no longer works. the symptom is that applications
attempting to play audio hang forever, and no audio is produced.
reverting this commit fixed the problem.
the issue only occurs if i have this set in /boot/loader.conf:
hw.usb.uaudio.default_bits=32
hw.usb.uaudio.default_rate=48000
removing these two settings makes audio work correctly again.
