Passthru device not found - touc - 2019-11-23
Hi,
A few years ago I configured my Shuttle XS35GT to use a USB -> S/PDIF converter and after some help (https://forum.kodi.tv/showthread.php?tid=199223) I was able to listen to movies in Dolby Digital in a 5.1 set-up. Recently I updated OS to Ubuntu 18.04 and installed the latest Kodi (18.5) and now I can't seem to get Kodi configured to allow the audio to passthru - there are no passthru devices available.
The device a Phiree U2 presents two devices: Device 0 is an Analog output and Device 1 is for S/PDIF output.

I can play audio OK using the Device 1:
aplay -D "iec958:CARD=U2,DEV=1" -r 48000 -fs16_le ~/Movies/ac3_the_other_side_44khz.wavIn Kodi, only the Phiree U2 Analog device (Device 0) is available. There are no passthru devices. I'm guessing it an Alsa configuration issue rather then Kodi, but I'm running out of talent. Any hints anyone ?
