| |
This patch makes it posible to use the bcm2835-audio driver on the Raspberry.
In drivers/staging/vc04_services/bcm2835-audio/TODO Michael Zoran says that this is to be done, in fact as we noted on https://bugs.debian.org/856505 without this patch the driver is not loaded and when loaded it doesn't do a thing.
After applying the patch on both 4.19.X and 4.20-rc5 you get the driver autoloaded and working sound on hdmi and on the minijack (selection done through amixer cset).
I'd like this patch to be applied so that people with a Raspberry can get sound out of it.
