When i enable the experimental gl driver (done via raspi-config, advanced options), then after a reboot, the dac+pro driver is not recognized anymore.
Do you know a way to both use the dac+ pro for playing hifi music and use the experimental gl driver with the application mixxx for dj-ing.
I use a pi 3, with up-to-date raspbian.
(did not do a rpi-update, because after that my pi won't boot anymore)
a piece of dmesg:
