Volume buttons don't work in 2.773

I’m on a raspberry pi 3b+ with justboom digi board with software volume control enabled.
Pressing volume up or volume down button in ui results in error volume Nan and no sound. Using slider control works as it should.

I can confirm that.
The hardwaremixer is not available.
The volume control does not work or is extremely unreliable, even with the softwaremixer. (can only be operated via the straight and the circle)
No mixer is set directly after the upgrade.
Not even after the factory reset and correct configuration of the dac.
A Hifiberry Dac is built into my test system. (rpi 1)

It can be dangerous for the speakers and the neighbors …


The same for me.
Rpi 4 and PHat dac

Sorry guys. We’re looking into it and release a fix for next release

Thank you for the great system!
The search results are much better now.
The new tag information is great!

Small correction or addition:
Yesterday 10.05.2020 I upgraded my Volumios. rpi 2 and 3 with Allo Boss 1.2.
These work perfectly!
All the errors described do not occur. (Volume problem, collection scan, …)


Same issue here. “Not a Number” error and the sound goes off when any of the buttons are pressed. The slider works fine.
Both on hardware mixer and software mixer install.

We found the issue and fixed it. New release coming this weekend

Hi, for me the buttons are working but they stop at 31…

This is very old non-fixed issue and happens with DACs.
Amixer with mapped volume scale (natural/logarithmic volume) rounds volume back to 30% when set to 31%.
Volumio should not rely on percentage volume instead of raw value.

So when volume is 30% and you press + (with volume increment 1), Volumio sets UI to 31% and Amixer is used to set volume 31%.
Amixer then calculates volume in percents and returns it rounded to nearest integer. Now Volumio gets volume level 30% but not update the UI. When you press -, volume is set to 29% because current volume was 30% (the reply from Amixer).

$ amixer -M -c 0 set Digital,0 30%
Simple mixer control ‘Digital’,0
Capabilities: pvolume pswitch
Playback channels: Front Left - Front Right
Limits: Playback 0 - 207
Front Left: Playback 144 [30%] [-31.50dB] [on]
Front Right: Playback 144 [30%] [-31.50dB] [on]

$ amixer -M -c 0 set Digital,0 31%
Simple mixer control ‘Digital’,0
Capabilities: pvolume pswitch
Playback channels: Front Left - Front Right
Limits: Playback 0 - 207
Front Left: Playback 145 [30%] [-31.00dB] [on]
Front Right: Playback 145 [30%] [-31.00dB] [on]

Is there a fix for this yet? I have the same issue. Only seems to happen with dac boards that rely on software volume control.

Michaelangelo, just curious, regarding the upcoming update which you said would be coming the next weekend. Which weekend was the update going to be released, or did I miss something? I’ve check for updates since reading your post and there hasn’t been one. The volume on my Justboom remote no longer works since version 2.773. The up or down button shows NaN then the volume goes to zero. I have a Raspberry Pi 3 Model B Rev 1.2, with an IQAudio DAC Plus, and using the software mixer.

Thanks for all of the great work!

So far the latest update to 2.777 seems to have fix it! Will test more this evening.

Thanks for addressing this issue!

I have a similar issue on. 2777, with Hardware mixer on my Piano 2.1 instance.
With 1 as step size, the volume does not go up and goes down with size of 2.
When I switch to Software volume control, step size 1 works perfectly.
