USB enumeration and sound card detection is not happening when XMOS XK-AUDIO-216-MC-AB board board is connected. Tried from both DUT USB port1 and port2
Steps to reproduce:
1.Flash the software on the DUT (Device under Test)
2. Make necessary chnages
3. connect XMOS board to the DUT
7. start playback from the Music APK
Observation: When the XMOS is connected ,the audio is playing from the DUT speakers .
XMOS device is not getting detected (observed the soundcard of XMOS board is not showing from adb command)
Audio playback is not coming from the XMOS XK-AUDIO-216-MC-AB board

Firstly, if you're starting a new design it would be recommended to use xcore.ai over xcore-200
Unsure what you mean by port1 and port2, theres only one USB device (micro-b) on the board (J11)
Which software have you downloaded? Which binary have you programmed?
(Steps 4-6 missing?)
When you say APK, this is an android app? Doe's the device work from windows or macOS etc - lets start with the basics...
You say "audio is playing from the DUT" but also the xmos device is not showing?
adb command confirms android I guess.. but still lots of questions here..
It wouldn't surprise me if your android device supported stereo devices only.
