Multi sound card

Unread post by sbynkln » Wed May 09, 2018 4:34 pm

Hello,
Is it possible to work with multi sound card (like HiFi Shield Plus, or usb audio adapter) integrated Odroid C2/(or other) and play same or different music for each card, I think this refers to multi zone application.

The HiFi Shield is just copy the output sound from usb audio adapter or HDMI.
So, to select output sound, you should select USB adapter or HDMI.

Is it possible programmatically, or is there any example of it. I was tinking it is not possible with android OS.

You can select audio output by editing the audio_policy.conf on /system/etc.

please check the reference. :)
