Topic: Chrome/Edge audio not working with CC UCX II

I'm switching from Windows to Linux on a daily basis and using CC mode to have audio working.
It seems that the Chrome-based Microsoft Edge (Chrome included) does not output sound in CC mode.
Similar experience with Tidal.

foobar2000 through the "Default : Primary Sound Driver" works fine.

Can somebody please check this configuration?
I'm running Windows 11 + Edge fully updated.

(tried to search, but CC is too short - perhaps it can be allow-listed by the forum owners)

Thanks! BR, -adi

Re: Chrome/Edge audio not working with CC UCX II

Is the device showing up in the device manager ?
Do you select it as audio output device in Windows audio settings loudspeakers configuration ?

Re: Chrome/Edge audio not working with CC UCX II

Having foobar2000 making sound on the "Primary sound driver" confirms the device is found and the default.

In device manager UCX appears as "Speakers (2- Fireface UCX II (.....))".
Manually checked the "Output Devices" screen in Control Panel and everything is correct.

CC stands for class compliant
Theoretically there is no reason why edge sound not comes thru.

Without the UCX connected the sound of the Edge browser comes thru the computer loudspeakers normal ?

Re: Chrome/Edge audio not working with CC UCX II

Theoretically there is a simple reason - bad implementations that can't handle devices that have more than a few channels...

With CC, the mode that is not working, there are actually only 2 inputs and 2 outputs.
So I wouldn't say it's a bad multi-channel implementation.

Switching back to USB brings back the sound in Edge.

Re: Chrome/Edge audio not working with CC UCX II

Page 98 in the user manual :

The Class Compliant mode of the UCX II is not compatible to Windows.
The UCX II will be detected, but automatic driver installation will fail.

Edit : Since the publish of the user manual, the firmware updates for this interface including new CC wich might be usable under Windows.
Make sure you have the latest firmware loaded.

The UCX II does not have a 2 in 2 out CC mode. See manual chapter 33.2. Lowest one is 8 channel I/O. And most probably you did not select any CC mode (in the OS, not the app) but use the default with 20 channels.
