Hi All,

Many thanks for the superb product with max2play! Love it and works so far with one exception and I hope that someone could help or point me in the right direction…

I have one speaker fully set-up without issues with an Hifiberry DAC light and external amp… no issues (squeezlite & bluetooth streaming) but does not look great.

So got second set as follows:

Set-Up
– rPi 3
– installed Hifiberry Amp2
– chose Amp2 at first installation
– added USB External Bluetooth dongle (as on-board was as bad as in many posts described)
– installed bluetooth
– turned off all audioplayers except Squeezlite
– disabled on-board bluetooth
– disabled on-board audio
– connected phone (Galaxy S7 & Galaxy A5) – both can connect without issues
– Note: Speaker attached is a „8 ohm – center speaker“ i.e. only connected to one speaker output of the amp2
– RPi is powered with the suggested 18V power adapter

Tested
– Squeezlite plays music perfectly fine (both phones)
– tried to use bluetooth streaming but no sound from either phone
– took off amp2 and played music via audio jack and internal soundchip (works fine for squeezlite & bluetooth streaming) = should not be the dongle…

– Wiped the card, started from scratch but no change… reading plenty of posts here but so far no luck…

Question is whether there is any particular known problem with the bluetooth streaming via amp2? Any settings that cause conflict or which i have to particularly look at?

Set-up looks identical to the one of the working speaker build previously…

So anything that I could look at to figure this out?

Many thanks in advance for any help!
Best
Aylon

Try adding „-C 5“ to the command line options of your Squeezelite to make sure it does not block the sound card for other playback.

Hi Heiner,

Many thanks for the reply but the flag is already set in my previous testing.

So this seems not to cause the issues.

Apologies for not mentioning it.

Many thanks

If you have shairport running please remove it and see if the problem persists.

Also, please copy the debug info from your Audioplayer plugin here as well.

Strangely did my previous reply just disappear … hence here the details again.

Shairport & DNLA were both already disabled.

From the DEBUG I wonder if the following is simply incorrect as I disabled on-board sound?

BLUEALSA_PLAY_AUDIOCARD=hw:1,0

should actually be

BLUEALSA_PLAY_AUDIOCARD=hw:0,0

If so, how do I change this value as I have only one option on the bluetooth streaming section and this one is chosen:

sndrpihifiberry – hw:0:0 – Mixer Digital – HiFiBerry DAC+ HiFi pcm512x-hifi-0 []

Full DEBUG output below and again many thanks for your help!

Hi Aylon,

You can try removing the disable tick in Raspberry Settings and rebooting.

Hi Heiner,

Thanks again but that unfortunately did not change it.

Tried following:
– enabled on-board sound & changes sqeezlite audioplayer [SL] to hw:0 = music from SL works fine but no sound via BT streaming
– added the dmix option = SL works fine but no sound via BT
– tried all three soundcard options on BT site = no soud via BT

last I upgraded kernel + updated all packages but still the Problem persists? I do not get any sound via BT streaming option?

anything else maybe to test or see what might be the case? I can SSH into the RPi if that would add any value with the right commands?

Thanks again
Aylon

Hi Heiner,

Used the fathersday to start from scratch again and this time with another RPi i still had flying around. While at first I had the same issue with the bluetooth streaming it is now working.

Seems as if the bluetooth streaming uses always the device #1 even if the on board sound is disabled and the AMP2 being at device #0 position.

However, my AMP2 somehow did not play via squeezlite first when on-board sound is not disabled and the card is #1. So I disabled on-board sound change hw:1 to hw:0 with the audioplayer and it played well. Bluetooth however not at this time. I the enabled on-board sound again and magically both, bluetooth and audioplayer worked well.

Strange but at the moment it is solved for now.

Many thanks,
Aylon
