This may be a related problem. Using OpenElec on Pi, I don’t suffer from the “pop” problem (it’s there but very subdued).

What I DO have is lot of background noise – it’s not far off zero DB s/n to my ear – during play out of the analog audio port. If I swap from USB WiFI to wired ethernet it’s quite a lot better, but still not great.

I’ve seen a lot of mention of using “cheap USB audio DACs” but no mention of specific models or chipsets, and I don’t want to end up in module/driver hell.

Thank you! It worked – no more audio pops, smooth.
Eternally grateful /magnus

sorry asked too soon, I just removed the comment tag that I put into the system.pa file and it has gone back to its normal popping behaviour at the start and end of tracks! preferable.

I applied Martin Klomp’s fix but now have constant popping at all times. How can I undo?

Thanks for the reply.

Too bad, I thought all audio, including movies, would be fixed :/

Using the Pi for TV and movies in the bedroom, at night, the audio pop noise is Very annoying – wakes up the neighbours

(and I use whatever the CoreAudioEngine default is – I don’t remember changing this…)

I still get pops from video files but am only really interested in audio files. I can live with a pop at either end of a movie, but it’s incredibly annoying for me in between songs.

Are you guys doing movie playback in XBMC without ‘pops’, after applying this fix?

It just doesn’t work for me – I have followed both the original instructions and Martin Klomp’s. Not matter what I try, I get audio pops at start and stop of movie playback.

Du you have CoreAudioEngine enabled or disabled (default) in Raspbmc?

Thanks

executed all those commands, still I can’t hear anything with the paplay command

Just wanted to add that first I installed the latest ‘release’ from 20121231 but that had an odd bug that would only play the first song in a playlist so I updated to the latest nightly, followed the above instructions and now everything is perfect and pop free
