Hi, I have been experimenting with USB audio devices recently and have settled on an USB device which seems to be a weird OEM device labeled by the german company CSL. The device announces itself on the USB as "0d8c:0102 C-Media Electronics, Inc. CM106 Like Sound Device". I am pasting the output of lsusb -v, aplay -l and aplay -L below and am willing to deliver any additional information that may helpful here. It is very important for me that I can use the optical ports that the device has for both recording audio to the computer and playing back audio from the computer. Amazon Link: https://www.amazon.de/CSL-Soundkarte-Lautsprecher-gleichzeitige-Audiogeräte/dp/B00KXAVBQY The device is recording audio just fine, from the analog inputs and from the optical input. What I have not been able to is playing back through the optical output. I have connected a Sony DTC-60ES DAT deck to the output, which does not seem to properly sync on the output. The "digital input" indicator on the DAT deck does not stop blinking which is an indicator of "no signal". I have tried playing around with alsamixer, but didn't find any fader for the digital output, nor did I find an output switch. I was also never able to stop the device from playing back from the analog output. Even when I select the IEC958 digital output in pavucontrol, playback continues from the analog output. I have tried: - mpg321 - juk - mixxx - audacity All of those with pulseaudio, with pasuspender active while tying to use plain ALSA, and I even made my first steps with jack. All I got was silence, or analog playbay, and never even a "yes, there is a signal to sync on" from the DAT deck. Are there any ideas what I could additionally try? Greetings Marc I apologize that the USB device is not the only sound device present in the machine, it does have on-board sound, an active sound link via DisplayPort to the Monitor and an CMI8738 PCI sound card that I am reluctant to pull without the new USB device working.
