Welcome to our community :slightly_smiling_face:.

Please try to enable the auto-conversion plugin.

That there are no controls in alsamixer might be a hint that drivers are limited, on the other hand the DAC is detected as such with all devices and channels :thinking:. The manufacturer does not provide info about Linux drivers or setup?

where can I get the “auto-conversion plugin”?

I have tested: if unplug “USB-DAC”, voice can output from 3.5 of PC.

Welcome to our community.

Most of the information could have been copied directly from SSH terminal via copy/past. Usually there is no need to create that much screen prints :wink:
