Hi,
Here's a new driver for both USB audio class (UAC) v1.0 and v2.0
devices, it would replace the current one. It focuses on reliability
and proper synchronization, including in low-latency configurations.
Our current USB sub-system has limitations that currently allow only
the following combinations:
- USB v2 devices on ehci(4) only
- USB v1 devices on uhci(4), ohci(4) or ehci(4) root hub only
If you have an audio device that is class compliant (aka vendor claims
it's "driverless" on MacOS) *and* one of the above host/hub/device
combinations then I'd be very interested in test reports. Especially
I'd like to know about possible regressions.
To test, apply this diff, rebuild the kernel and set:
sndiod_flags=-f rsnd/1
in /etc/rc.conf.local (assuming your uaudio device shows as uaudio1 in
dmesg). Then do your regular audio work, let me know how it works and
send me output of:
dmesg
mixerctl -v -f /dev/mixer1
If something is broken, please check if this is a regression.
Hi Alexandre,
Sorry for being late to the party. With this patch audio playback with
my Schiit Bifrost DAC works, however I get an error with the output of
mixerctl. This DAC didn't work before. Please see dmesg and mixerctl
output below.
Kind regards,
Martijn Rijkeboer
