Experiencing constant disconnects during audio stream on Raspberry Pi about airsonos HOT 7 CLOSED

@loretoparisi It may depend on what type of pi you have, but this should give you the info you need - https://www.howtogeek.com/269202/how-and-why-to-overclock-your-raspberry-pi-microcomputer/

Something I didn't mention above. I'm running AirSonos on a raspberrypi while encountering these issues.

I've done a little more testing and found the following:

• If I run AirSonos on my macbook, everything works fine (I can stream w/o disconnections to all my Sonos speakers)
• On the pi, I see that CPU is maxed out at 100% while attempting to airplay (and continues through the disconnects)
• I don't see any processes dying on the pi while the CPU is maxed, but I'm thinking that CPU could be the culprit

Going to continue digging, but any help or suggestions are much appreciated!

hi dgrizzanti,

I have also tried running airsonos on a raspi, with similar results. Apparently the hardware is not potent enough to encode the audio on the fly (at least not with the present software settings) and that's why the audio gets choppy. There was some discussion on using special hardware in the pi here: stephen/nicercast#2

Somebody got it to work here:

So it seems possible...

@knusprig55 That is the article I found that made me go down the raspberry pi path. I originally was using another method with shaiport and VLC to achieve the AirPlay support through the pi. This seemed like a cleaner option and the previous method would crash all the time.

I eventually got this working by over clocking the pi. Not sure if anyone else has any experience with that. There are few "supported" modes that are available in raspi-config. Turbo being the one that seems to work for me.

Hmm, this is a known issue, as I've repro'd the same problem - it seems the lame mp3 audio encoding is too much for the pi to handle at times. One other possibility could be to try using this method for pure PCM streaming, which would bypass the mp3 encoding process: #26

The downside there, would be increased bandwidth costs, since a PCM stream is much bigger, which might also cause parts of the audio to cut out.

I was able to get this working as stated above by over clocking the pi, so I'm going to close the issue

@dgrizzanti Hey David, how did you manage to overclock the pi? thanks!
