REW Beta Release USB Input device is not available for cal file (V5.20 beta 23 MacOS)

[Gdenich]

Dear John,

I have recently updated to the latest V5.20 beta 23 for MacOS, and have found that I can not assign the calibration file to my mic device.
I use C-media USB audio card as input and output device.

In the preferences pane I can choose the "USB Audio device" as output device, and assign the corresponding calibration file on the "Cal Files" pane.
As for the the same "USB Audio device" as INPUT device, I can only choose "Default input" or "MICROPHONE" on "Soundcard" pref. pane, and it is not listed on the "Cal files" pane. The Macbook's internal mic appears here, but USB card mic not.
What can be the problem? In previous versions I could successfully use this card with REW, but now I can use the MIC only without the calibration file.
Below you can find the prefpanes screenshots and soundcard_debug.txt.

Regards,
Denis

Try setting the sample rate to 48 kHz. The "MICROPHONE" input on the C-media doesn't appear to be offering any input channels, hence the empty channel select boxes.

I have changed to 48 kHz, a new device appeared in "CAL Files" for output, but still no for input

Looks like the C-media mic input is mono only, there might be some issue relating to that. I'll investigate further.

I've made a new build which should fix that.

John, thanks a lot for the support. I'll be looking forward for a new build to be available for download.

I have just installed the new V5.20 beta 24 build, everything works perfectly now. Thank you!
