>Description:

Hi, audio using an external USB DAC appears to be broken in the latest
snapshot, as compared to 6.0 (I do not have a stable 6.1 box to test,
unfortunately).

On 6.0, I can plug in the DAC (I have tried 3, and it's the same with each
one) and it works. On the latest snapshot, the DAC is recognized by the
kernel, but when I try to play sound through the device (using e.g. aucat -i
file.wav -f rsnd/1) I get the following errors in /var/log/messages:

May 12 15:17:20 work /bsd: uaudio_chan_open: error creating pipe: err=INVAL endpt=0x03
May 12 15:17:20 work /bsd: audio1: failed to start playback

>How-To-Repeat:

1 - Plug in a USB DAC (I've tried the Audioquest Dragonfly, the Fiio K1 and an
Asus one)
2 - Run aucat -i <wav file> -f <device name>

I've also tried running sndiod -f snd/1 and get the same issue.

Thanks, and my apologies if this is not a bug but a mistake on my end, but I
spent quite some time investigating and came up with nothing.

Your dmesg (quoted below) says you have both ehci(4) and xhci(4) USB host
controllers. Try plugging into a USB 2.0 port instead of a blue USB 3 one.

See http://marc.info/?l=openbsd-misc&m=149432514508256&w=2

Re: USB Audio appears broken in latest snapshot (uaudio_chan_open: error creating pipe)

Sorry I missed the previous bug report - I searched for both the
dragonfly and the error message but I think I stupidly only searched
misc@. I've just tried every port on both the laptop and the dock and
none of them work. I've also rebooted and disabled xhci with boot -c but
that stopped all usb working. I'll be taking the laptop home tonight so
I can try with a usb 2 hub and see if that works.

For now, at least I know the issue is not the OpenBSD version and the
bug/lack-of-feature is known. Thanks for your help.
