It’d be interesting to give it a go. The interesting thing here is that all similar complaints when a DAC disconnects after X second are coming from Google Pixel users…
After discussion we had yesterday, a plausible cause is that after that update android is requesting access to the usb DAC periodically, and that causes the disconnect from our driver. It works with the AAudio driver, because that is the thing requesting the access.
The fix to disable the automatic usb audio routing would be interesting to try. The other fix, about disabling data transfers through usb may accomplish the same thing, but it harms other use cases, so I am not going to ask you to do that
Nevertheless, may I ask you to try the first thing – automatic usb audio routing? Here is a comprehensive guide to do this – link.
Thanks!
