>Description:

When trying to play audio through the uaudio device, I get the following
error messages from the kernel.  In addition, the audio does not play and
the player, mpg123 in this case, gets write failures.
Kernel messages look like:

[   425.807534] uaudio0 at uhub1 port 1 configuration 1 interface 0

[   640.657534] audio1: device timeout
[   643.657534] audio1: device timeout

>How-To-Repeat:
	Plug in one of these USB devices to a NetBSD-9.1 system and try to
send audio, using mpg123, mplayer, or something, through its association
audio device.
It's worth noting this device works perfectly under NetBSD-3, NetBSD-4,
NetBSD-5 and FreeBSD-12.  So, I think this is probably a regression from
the new audio subsystem that went in for NetBSD-9.x.  I've tried plugging
into different  USB ports on the system, with the same result.

 	hello.  This appears to be a larger problem  with USB audio  as I just
 tried playing audio with a different USB audio device.  this one
 demonstrates the same errors as the C-Media device.  It probes as follows:

 	hello.  Here's some more data on this issue.  The problem appears to be specific to the
 xhci(4) driver.  Specifically, if I boot an older machine with NetBSD-9.1 with an uchi(4) USB
 chip in it, the uaudio driver works fine with the C-Media USB audio device.  Of course, it's
 also an I386 machine, not an amd64 machine but I hope that isn't the difference that
 demonstrates the problem.  
 So, I will now investigate potential issues with the xhci(4) driver.
 -thanks

 Any updates or ideas on this one?

 I'm running into the same problem I guess.  My >10 year old system died
 recently and trying to use a C-Media usb device with a relatively new
 motherboard and get the same symptoms:

 [     4.614518] uaudio0 at uhub4 port 2 configuration 1 interface 0

 [     4.724559] uhid0 at uhidev0: input=4, output=4, feature=0

 It has an xhci as well:
  > dmesg |grep xhci

 and the same error with mplayer or any audio:

 AFAIK xhci(4) on NetBSD-9 does not support isochronous transfer
 used in such as uaudio and uvideo.

 -current has xhci isoc support.
