Hi,
I am trying to capture video and audio using a USB device called
"GrabBeeX+ Deluxe." While I am able to capture video successfully, I am
unable to get any audio output from the device.
After checking the kernel log, I noticed that this device may not be
fully supported. There appears to be support for a non-"Deluxe" version,
which has a different USB ID.
Could this be the reason why the audio is not working?
Below, I have included relevant system information and kernel log
details for reference. Please let me know if you need more information.
Best regards,
Olli
