[Arm-dev] Alsa and Pulse conflicts in Raspberry Pi 2/3

[Hugo De Zela]

Hi all, I've just finished doing some maintenance on a few of our 
systems (we use them for digital signage) and noticed that all the ones 
I've touched today have lost audio.

After some digging I found that the issue is Pulse Audio being installed 
via some package dependency; apparently on the Rpi Pulse conflicts with 
Alsa and audio stops working when they're both installed. Not 100% sure 
what package pulled in Pulse (kinda putting out fires trying to revert 
changes at the moment), but I'll look into it later.

Just as a general FYI to anyone having random audio issues with an Rpi 
2/3, check if Pulse is installed. Removing it and rebooting should fix 
the issue.

Cheers, HDZ
