I have been getting popping noises on my Pi4 headphone output when playing FLACs (not radio). To stop the popping I have tried both "-a 120:4::0" and "-a 16384:4096::0" and both seem to work! A while ago I had problems with the sound breaking up and I added "-a :::0" which fixed it. But can anyone explain what this actually is doing? The Wiki says: -a <b>:<p>:<f>:<m> Specify ALSA params to open output device, b = buffer time in ms or size in bytes, p = period count or size in bytes, f sample format (16|24|24_3|32), m = use mmap (0|1) Frankly I have no idea what this means, which buffer, whether the specified numbers are in ms or bytes, what period, what is mmap, and will there be a delay on the audio output as a result!? And more importantly why do I need to specify this on my system which couldn't be simpler, or Is there something more sinister going on? Surely defaults should work on a simple system? - Pi4 - Raspbian 10 (Buster) - ExecStart=/usr/bin/squeezelite -o plughw:CARD=Headphones,DEV=0 -n Pi_SqueezeliteService -C 5 -a 120:4::0 - LMS 8.1.2 - 1624550702 @ Thu Jun 24, 2021 - Squeezelite v1.9.9-1386 - Also 2 other SB3s, but these were unsync'd during testing.
