Hi all, nexus 7 2013 lte and WiFi model, 5.1.1 with timurs Kernal installed in my car.
I've got a board that has a 5v 3a power supply going to a otg y cable. Usb hub plugged into y cable and dac plugged into hub.
I've just swapped from a miniDSP MiniStreamer which is a usb to spdif coaxial sound card. This worked perfectly, I could unplug and replug the otg cable or turn power off whenever I wanted and it would always be recognized and be used by Android through Spotify, power amp etc.
I just changed my processor and it takes an optical spdif input so I changed the MiniStreamer to a hifimediy sabre u2 dac which also does optical spdif out.
I found to get the sabre u2 to work at all, I have to turn the tablet off, connect the dac and power to it, the turn the tablet on. This takes a while to do.
As soon as I either disconnect the otg cable or turn power to the dac off and back on or the tablet goes into its Fi sleep mode (when car is turned off) my tablet no longer uses it for audio but reverts back to tablet speakers.
In the power event manager it still shows the usb hub and the dac as being connected.
Would greatly appreciate any help, as it's my only source for audio in the car.
Apologoes if it's in the wrong place, I've not spent much time on this forum so not sure where everything is.
