Hello everybody,

I’m having this funny problem that on my latest multi room addition the music sounds like the singers are in a concert hall. I hope you guys find a solution for me.

Let me explain my setup:

A raspberryPi 3 works as squeezebox server.
A couple of Pi2 with amp+ hifiberry’s are working as squeezeplayers
the latest entry is a Pi2 with amp2.

The latter works, but as mentioned befor, not so good.

I guess it is some setting that is not ok, but I don’t know which one.
In the advanced options from the squeezelite settings I use
– sysdefault-snd_rpi_h
– ALSA param: 2000:4::
– the other fields are blank.

What do I need to do to get rid of the „echo effect“ on the music?

Does someone know?

Hi Joris,

Please try replacing the ALSA parameter with „80:4::“ and adding „hw:1“ to your command line options (if you do not have your build in audio removed in the Raspberry Settings, if it is removed use „hw:0“). After saving, please also reboot your device.

Hi Heiner,

Thx a lot for your help!
I’ve tried your suggestion (ALSA parameter with „80:4::“ and adding „hw:1“ in command line ) but I get this error:

-R -u [params] Resample, params = ::::::,
recipe = (v|h|m|l|q)(L|I|M)(s) [E|X], E = exception - resample only if native rate not supported, X = async - resample to max rate for device, otherwise to max sync rate
flags = num in hex,
attenuation = attenuation in dB to apply (default is -1db if not explicitly set),
precision = number of bits precision (NB. HQ = 20. VHQ = 28),
passband_end = number in percent (0dB pt. bandwidth to preserve. nyquist = 100%),
stopband_start = number in percent (Aliasing/imaging control. > passband_end),
phase_response = 0-100 (0 = minimum / 50 = linear / 100 = maximum)
-D [delay] Output device supports DSD over PCM (DoP), delay = optional delay switching between PCM and DoP in ms

-L List volume controls for output device
-U Unmute ALSA control and set to full volume (not supported with -V)
-V Use ALSA control for volume adjustment, otherwise use software volume adjustment
-Q Sync local ALSA volume changes with Squeezebox Server Volume when using -V option
-B Use to set PowerOn/Off Player on status of connected Bluetooth-Speakers (only for Pulse Audiooutput)
-I Squeezebox Server CLI Port (optional). Default 9090
-X Use a GPIO Button to switch between Play and Pause - works well with rotary encoders with button for Volume and Play/Pause
-z Daemonize
-Z Report rate to server in helo as the maximum sample rate we can support

Also with HW:0 I get the same. And even an message at the hifiberry page that the soundcard is located at HW:1

What shall i do now?

Hi Joris,

Please try removing the ALSA parameters completely. Also make sure there are no additional blank spaces or any other irregularity.

Hi Heiner,

Same result with the ALSA parameters removed. If I leave them in (the 80:4::) and I remove the command line option, then it works again. But with the same weird audio result. The singer sounds like he’s in a big hall or bathroom or whatever.. 🙂

Hi Joris,

I do, this seems to indicate your sound card is somehow deactivated. Please selecting „none“ in the HiFiBerry Plugin, rebooting, selecting AMP2 again and rebooting once more.

Dough, I had to ad:

Unfortunately, still the same weird metallic sounds

Okay, this output looks good. What power supply do you use for the AMP2?

Joris

I use my ‚lab‘ powersupply. It should be fine.
