Horrible - Raspberry Pi + Wavelength Audio Proton

yoghurtlidlicker · December 16, 2013, 1:56pm

Hello,

I’m long time user of RaspyFI (It was working nearly perfectly).
Just installed Volumio on my Raspberry Pi and it’s horrible!
I tried every single kernel and c-media fix.
It’s so much distorted - Unlistenable even.

Please help!

This is very likely to happen because of NAS mounts settings. Try to decrease Rsize and Wsize in advanced, libray settings.
Let me know!

yoghurtlidlicker · December 16, 2013, 2:13pm

thank you for such a fast respond!

I’m using external powered USB drive.

volumio · December 16, 2013, 2:16pm

Has it finished indexing your database?

yoghurtlidlicker · December 16, 2013, 2:23pm

Yes indeed

volumio · December 16, 2013, 2:26pm

Connected through a powered USB hub?
Try to change resampling algorithm, if enabled. Or try to set Mixer -> disabled

It’s EXTERNAL RAID DRVIE with PSU.
I was using it with RaspyFi without any problems.

Airplay and WebRadio is distorted as well.

yoghurtlidlicker · December 16, 2013, 2:31pm

Resampling - disabled
Mixer is Disabled or Hardware - doesn’t change anything.

It’s sounds like it’s underwater + a lot of cracks/zaps.

Now I wish I had 2nd SD Card with RaspyFi…

volumio · December 16, 2013, 3:15pm

Do you listen to Flac or Wav or Mp3s? Also, does webradios sound normal?

yoghurtlidlicker · December 16, 2013, 4:46pm

WAV
as I mentioned before, WebRadios and AirPlay is distorted as well.

Cheers

I cannot replicate your issue. Please, try to stop all playbacks. Then reboot. Then start just one webradio (disconnect Airplay from the pc or phone you were using) and let me know.
Could be that mpd and shairport are competing for Pi’s resources

and please if you can, just report the output of

cat /proc/asound/card0/pcm0p/sub0/hw_params

Sure we’ll get this sorted out

Hi guys, another ex-RaspyFi user experiencing Volumio problems described in this thread.

I am using audiophilleo2 as my “DAC”. Here is asked output from my Volumio PI:

root@volumio:~# cat /proc/asound/card0/pcm0p/sub0/hw_params access: RW_INTERLEAVED format: S24_3LE subformat: STD channels: 2 rate: 44100 (44100/1) period_size: 5513 buffer_size: 22050I can additionally mention that sound crackling occurs with NAS mp3 files but NOT with flac and m4a files from the very same NAS.

Web radio also crackles.

Finally, my dmesg is full with such “delay” messages:

root@volumio:~# dmesg | tail delay: estimated 0, actual 177 delay: estimated 0, actual 176 delay: estimated 0, actual 176 delay: estimated 0, actual 177 delay: estimated 0, actual 177 delay: estimated 0, actual 176 delay: estimated 0, actual 176 delay: estimated 0, actual 177 delay: estimated 0, actual 177 delay: estimated 0, actual 177Thanks in advance for your help and keep up the good work.

Arrivederci da Sarajevo

Would be amazing! I was so excited about this new release…

how can I report it?
When I use this command I’m getting:

root@volumio:~# cat /proc/asound/card0/pcm0p/sub0/hw_params closed

yoghurtlidlicker · December 17, 2013, 7:39pm

I tried it again

root@volumio:~# cat /proc/asound/card0/pcm0p/sub0/hw_params closed root@volumio:~#

Same issues here with the M1 dac.
Isn’t it possible to downgrade the kernel to raspyfi ?

Ape was supported by raspyfi. Why not in volumio?

Just installed Volumio on my Raspberry Pi (previously had RaspyFi installed) and it is connected to a Schiit Modi DAC.

“default” settings":
mixer type - disabled
audio buffer -2048
buffer before play - 20%
audio output format (resampling) - disabled
sample rate converter - fastest sync interpolator

I have tested with three different audio files:
MP3
FLAC 44.1/24
FLAC 96/24

Default settings have resulted in continuous crackling/hiss with all three formats. not listenable.

However when I changed audio output format (resampling) setting, the following happened:
16bit / 44.1 khz - clear playback, no crackling or hiss on all source files
24bit / 44.1 khz - significant crackling / hiss on all source files
24bit / 96 khz - only occasional crackling on all source files, mp3 is worst

I verified the bitstream in each test case using the command: cat /proc/asound/card0/pcm0p/sub0/hw_params

My conclusion is that if I am getting better playback when sampling at 24bit/96khz, its not a resource issue with the raspberry pi but rather some other issue in the Volumio code.

Me too - migrated from Rasbyfi, severe sound dropouts over airplay, airplay loses connection.

Great Job though…Let me know what you need to help fix this -

out put of cat /proc/asound/card0/pcm0p/sub0/hw_params is

Sound quality (!) with resampling is even worse…

yoghurtlidlicker · December 18, 2013, 4:47pm

it’s 3rd day without music…
I’m gonna go mental soon ;D

iorr · December 18, 2013, 4:52pm

I can confirm that resampling to 16 / 44 works (for me).

Audiophile webradio doesn’t work.
Is there anybody out there who knows the new pls-data?
