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. card 2: CMI8738 [C-Media CMI8738], device 0: CMI8738-MC6 [C-Media PCI DAC/ADC] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: CMI8738 [C-Media CMI8738], device 1: CMI8738-MC6 [C-Media PCI 2nd DAC] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: CMI8738 [C-Media CMI8738], device 2: CMI8738-MC6 [C-Media PCI IEC958] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: Device [USB Sound Device], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 [2/5014]mh@fan:~ $ sudo aplay -L iec958:CARD=SB,DEV=0 HDA ATI SB, ALC892 Digital IEC958 (S/PDIF) Digital Audio Output iec958:CARD=CMI8738,DEV=0 C-Media CMI8738, C-Media PCI DAC/ADC IEC958 (S/PDIF) Digital Audio Output iec958:CARD=Device,DEV=0 USB Sound Device, USB Audio IEC958 (S/PDIF) Digital Audio Output Hi, In order to get output to the digital output, you need to use the "iec958" device. E.g.: speaker-test -c2 -d iec958:CARD=CMI8738,DEV=0 --rate 48000 Note that you also appear to have a digital out of the SB card, so you need to select the card when outputting. You might also need to mess with AES0 settings. Google for that.

All my DAT recorder drives are broken, the only reason to keep them is to have DACs and ADCs I could use via S/PDIF, in addition to the analog I/Os and ADAT I/Os of my audio devices, just in case I ever should need additional I/Os, which actually never happened. You already could get a semi-professional OOTB Linux compatible, especially class compliant audio device, for half of the price even a second hand DAT recorder does cost. I could use my broken DAT recorders converters via S/PDIF with my audio devices. 1. One of my broken DAT recorders is a Sony consumer DAT. Better discontinue to use a consumer DAT recorder, soon or later they all suffer from drive issues. 2. If you wish to continue using a DAT recorder in combination with your computer, then consider to spend more than 23,85 € for your computer's audio device. It isn't worth the hassle to save on the wrong things. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
