Volume Contol not working

[atze09]

Hey guys,
I installed according to documentation on NTC CHIP with usb sound card.

I start with:
./spotify-connect-web.sh --username name --password pass --name chip --device Device

it works playing sound on internal audio jack and on usb sound card, but volume change is not possible.
Can anyone please help me out?

Is not working propely.
Do i need to change the mixer?

What device are you using?

[atze09]

I use the usb soundcard "front:CARD=Device" with this line:

./spotify-connect-web.sh --username name --password pass --name chip --playback_device front:CARD=Device --mixer_device_index 1

[ghost]

No I mean Rpi 1,2,3, zero etc

Sorry.
It is a NTC CHIP, which in my opinion is the ideal device for multiroom/spotify.
I already installed shairport-sync from mike brady, this is working properly with volume control.

[atze09]

Ca anyone help me in a deeper explanation of those arguments:
--mixer_device_index MIXER_DEVICE_INDEX
alsa card index of the mixer device
--mixer MIXER, -m MIXER
alsa mixer name for volume control

[ghost]

Ah, sorry. I haven't used one of those, I just know they use Allwinner. I have only used the chroot and the precompiled with dependencies on the RPi3. Have you tried both chroot and the other one?

[atze09]

No i haven't nearly everything is working, exept volume control.
How could chroot help me get it working?

[atze09]

Now i now what is the root cause, i had to change the following line from.
mixer_volume = int(mixer.getvolume()[0]*655.35)
to
mixer_volume = 1 #int(mixer.getvolume()[0]*655.35)
Because i got teh following error when i start spotify connect.

Loading Spotify library... min_volume_range: 0.0 Using libspotify_embedded version: master-v1.5.0-gfba69d71 SpInit: 0 Traceback (most recent call last): File "main.py", line 56, in <module> connect_app = Connect(web_error_callback, web_arg_parser) File "/usr/src/app/connect.py", line 87, in __init__ lib.SpPlaybackUpdateVolume(mixer_volume) OverflowError: integer 112756244 does not fit '16-bit unsigned int'
How can i do it without changing the volume to 1??

[atze09]

Saw some fixes should i try any of them?

[atze09]

With the fix i get the following pylast error:
Traceback (most recent call last): File "loader.py", line 3, in <module> File "runpy.py", line 180, in run_module File "runpy.py", line 72, in _run_code File "/root/spotify-connect-web/main.py", line 15, in <module> from connect import Connect File "/root/spotify-connect-web/connect.py", line 9, in <module> from console_callbacks import audio_arg_parser, mixer, error_callback, connection_callbacks, debug_callbacks, playback_callbacks, playback_setup File "/root/spotify-connect-web/console_callbacks.py", line 9, in <module> from lastfm import lastfm File "/root/spotify-connect-web/lastfm.py", line 3, in <module> import pylast ImportError: No module named pylast

Can anyone help me?

Are any of these issues present without the USB soundcard? What soundcard are you using? Which chipset does it use?

Edit: You could also try https://github.com/plietar/librespot

[atze09]

But this is not spotify Connect or?

Pylast could not be found, is it an issue oft THW allwinner CPU?

[ghost]

I'm not sure, though I believe its better supported on the Raspberry Pi.

[atze09]

Yes in my pi's it is running smoothly. But the NTC chip is thr cheaper alternative!
Maybe the developer can support me?

[ghost]

I only know that allwinner have not had a good relationship with the open source community https://en.wikipedia.org/wiki/Allwinner_Technology#Linux_controversies You might want to try the CHIP forums as well

Try the latest build
https://github.com/Fornoth/spotify-connect-web/releases/tag/0.0.4-alpha
plus the options --playback_device 'default:CARD=sun4icodec' --mixer 'Power Amplifier'. That's what I use on my CHIP.
