Thanks, good to know, it's the remembering that's tricky :rolleyes::)

thanks. 


Code:

general = 
  {
ignore_volume_control = "yes";
  }

 

in /usr/local/etc/shairport-sync.conf did the trick

I don't know if pCP uses the default settings

https://github.com/mikebrady/shairport-sync/blob/master/scripts/shairport-sync.conf

Look at line #35

I think I have (previously in another thread,somewhere) read a post by
paul- say it is better to utilse the Plugin by philippe44 .

I might be wrong on that :rolleyes:

[SlimDevices: Unix] squeezelite big volume difference: LMS vs shairport-sync

[my1704]

I recently started using piCorePlayer with LMS, squeezelite and
shairport-sync all on same rPi4. The pi is on ethernet in LAN. 

Squeezelite sound goes out thru the rPi USB to a Benchmark Audio USB
DAC1, feeding a Bel Canto SEi40 integrated amp. The USB DAC has an
analog volume knob controlling vol on it's RCA outs. The Bel Canto amp
has front panel volume control with IR remote. 

I have not researched or experimented to find the optimal signal path
gain setup, but I currently get quite good sound running as follows:
digital volume output on LMS/Squeezelite I set to full, DAC analog
volume control also at full, and then end-of-path volume controlled at
Bel Canto amp using its remote or front panel ctrl.

Problem is when I switch to the squeezelite source to shairport-sync,
usually with a mac or iPhone playing browser/youtube or VLC vid or
audio. In the mac system prefs I select sound output as
piCorePlayer-Airplay. Even if I set the digital output volume on the mac
to full, and leave the DAC analog volume unchanged at full and the
volume unchanged at whatever it was with LMS source, the final volume
drops substantially, i'm guessing at least 10-15dB.

in the Shairport-sync settings I have the same audio device text I have
in the Squeezelite player settings: "hw:CARD=B10,DEV=0".

1) Is there some setting I can tweak to get shairport source volume to
come out similarly to LMS source volume?

2) Also although it seems to work (volume drop aside), I am a little
unsure about how squeezelite player's source is actually switched to
shairport. I don't see any explicit source selector control on the
piCorePlayer GUI.  When I select mac or iPhone sound output as
piCorePlayer-Airplay, I presume that during the handshake it just forces
to squeezelite player to drop the LMS source in favor of mac/iphone. Is
this correct ?
