Build Identifier: 

Fairly early in the merge window for 4.6 kernels I started having problems with my usb headset on i686. Today I checked on an x86_64 system and neither my usb headset nor usb sound bar showed up in pulseaudio's volume manager when using a 4.6 (rc2) kernel, but both did under a 4.5 kernel. Under the 4.6 kernel they do show up under lsusb.

Reproducible: Always

This is with a 4.6 kernel. You can see two sound devices (sinks) that aren't usb. I'll rerun under a 4.5 kernel so you can see the difference.

You can see there are 4 sinks listed in this case. The two extra sinks are the usb sound devices that did not show up under the 4.6 kernel.

Similar problem fixed for me here with rc2.gi2.1 (or to be precise git2.2  the non-debug build).
I believe the series causing the issue got partly reverted upstream, to potentially reappear later with more fixes.
Comment 6 Bruno Wolff III 2016-04-06 18:54:58 UTC 
For me 4.6.0-0.rc2.git2.1.fc25 works. Are you sure you tried rc2.gi2.2 and not rc2.git1.2? 4.6.0-0.rc2.git2.1.fc25 hasn't even finished its arm build yet. If so you should be able to close this. I don't want to just yet if it may only be fixed for some devices.

The x86_64 build is the first to be ready as usual. One could only wait for arm so much...

Closing.
