  • Optical Output / USB DAC Issues

Hi all-
I am having difficulty getting my MatchUP 10 DSP to recognize an optical signal from the DUDU 7 head unit that I installed this weekend. The Match does not recognize the SPDIF signal at all when coming from the back of the M7. If I use a USB-SPDIF adapter, the match will get a signal and play music from the stock local music player, as well as Spotify. It does not play radio, car play, streaming bluetooth from my phone, or bluetooth call audio.

If I open car link for car play, the local music player stops, and I have to reboot the head unit in order to get music to play again over the USB-SPDIF adapter.

Are there any settings that need to be adjusted aside from enabling USB audio to get this to work system-wide?

Cheers-
Addis

1) Check the quality of the optical cable, if it works, it should glow red.
2) Audio transmission via USB is possible only from players. Radio, Bluetooth calls, system sounds (for example, navigator) they won't work.

Thank you so much for the reply- the optical cable is brand new and glowing red. It is working with the USB to SPDIF adapter, so it should work with the optical output of the stereo.

Thank you for the info in the USB DAC limitations.

Does SPDIF passthrough have to be enabled to get a signal?
