Hi
I have a three Raspberry Pi setup. The Pi3 that runs Squeezebox Server has a Hifiberry Digi+. The other two are Pi2 that has Hifiberry Amp+.
The problem is I cannot get any sound when playing the tunein radio on the two Pi2 that has the Hifiberry Amp+. I can play music on the Pi2 from a hard drive attached to the Pi3 Server and can play radio and music files on the Pi3 Server but just not on the Pi2 that has the Hifiberry Amp+ attached. Iam using LMS

Where can I start looking for this problem?

Here is the debug file from one of the Pi2 —

Hi CB672,

What radio channel did you try?

Are your Pi 2’s connected via ethernet or WiFi?

Have you tried synchronizing the Pi3’s stream with the other two? If so, what were the results?

Hi Heiner

I am using wired connections. I did some more playing around and found a lot of other radio stations that play on both the Pi Players. The radio station I was trying to play is 94.7 | 947 (Top 40/Pop) based in South Africa. I noticed that the bitrate is 64k, the other stations that I could play on both players were either 48k or 128k. Seems like there could be a problem with the 64k bitrate. I have synchronised the players with no problems.

Thanks
Clyde

Hi Heiner

Any update as to why some radio stations do not play through the the Raspberry Pi using the Hifiberry Amp+? I tried setting up the Pi with the Amp+ as a Server but still have the same issues.

Thanks
Clyde

Please try adding the hardware volume control.

HW volume is -o hw:0 -V Master if you do not have built-in audio activated.

You can also check the parameters list to see whether adding another might help your situation: https://www.max2play.com/en/wiki/command-line-options-for-squeezelite/
