Hi, and thanks for your reply!
With:
sndiod_flags="-f rsnd/1 -f rsnd/0"
in /etc/rc.conf.local sndiod does indeed appear to try to make the uaudio0
device the
default, however when I try to play audio (vlc, chrome) I now see the
following in /var/log/messages:
Sep 20 14:07:40 obsd /bsd: uaudio_chan_open: error creating pipe:
err=INVAL endpt=0x01
I happened to have on hand another USB DAC so tried something similar with
it and saw almost the same error:
Sep 20 14:32:32 obsd /bsd: uaudio_chan_open: error creating pipe:
err=INVAL endpt=0x02
I've included output of `usbdevs` and `audioctl` below. Might this be an
issue with USB audio and USB 2.0 hubs?
