Raspberry Pi 2 - popping audio

Hello all,

Thanks for reading this.

We have a Raspberry Pi 2 and the audio output from the jack is popping. USB and HDMI are fine.

Is this fixable?

Much appreciated!

I'd take it back for replacement. It's still going to be under warranty.

I don't think it is a issue with the unit. The Jack output is known to have had issues but these were officially fixed in an update (i'm using Raspbian)

I've run apt-get update and upgrade but its still popping during playback.

I've tried various media players, including MPD, mplayer and banshee

sudo apt-get install rpi-update

then run:-

sudo rpi-update

I ran that and the firmware updated from 1.18.11 to 1.18.13 but I cant notice any difference in the audio.
I looked at the changelog on github and the changes don't seem to be relevant.

I contacted someone who is a bit of an expert and will wait and see how he replies.

Thanks

The info is only a few days old. Do you think it is the same issue you're having?

Good find. Thanks

I'm not sure if its the same issue as I'm not getting the same error message as he is and his sound is "stuttering extremely (unplayable)" whereas i'm only having occasional popping (every few seconds) which is playable but just gets annoying.

However I will try roll back the packages if I get a chance and report back.

Popping playback is often an indication that there is a higher priority process pre-empting the audio playback. It might be network access; the Pi has very little on-board memory and no spare horsepower. If you are playing back MP3s from across a network, try unplugging the network, play from a USB stick and see if the problem is remedied.

I have ensured that that firmware update was installed but i was still getting the issue. I have not tried using Pulse.

Either way, thanks all for your suggestions. I ended up going for a USB DAC to workaround the issue which as you say is quite common for the Pi.

You could continue on working with this contact who has one or two of them. He's very busy right now though. But today he suggested I post his link.
