I just experienced this for the first time after using Roon for a few months without Incident.
I have a Roon Core On Windows 10. I had another Windows 10 machine that I was using to select and play tracks play tracks. The endpoint was my NAIM Unity Atom.
Whenever I tried to drag the slider down it would just go back up again. It wouldn’t jump up (immediately to 100) but quickly tick up to 100 every time I reduced it.
It did not matter if I dragged the slider down or clicked “MINUS” repeatedly. It did move it down but then went straight back up again.
After turning the NAIM off and restarting the Core it’s been fine since.
Luckily I was sat next to the Atom so I was able to turn it off.
If it had damaged my £1000 Acoustic Energy Speakers I would have been quite ■■■■■■.
I can confirm that I had turned the volume up by clicking the “PLUS” icon a few times on my Windows 10 PC with my mouse. It then just carried on ticking up. It was like it registered 10000 clicks or something.
I have Geforce Shadowplay installed on my PC so i’ll try and record it next time.
It’s only happened once in a probably about 100hrs of listening and it may never happen again.
Just letting you know it has happened though.
Of course there was an update yesterday/today on all of my devices.
Could be a system damaging problem so worth investigation.
Lumin Firmware 13 introduced a Max Volume % setting adjustable in Lumin iOS app 6.1.17. Using this feature Roon Volume 100 can optionally be rescaled to a lower actual volume to protect your speakers. In addition, the new Leedh Processing Volume uses a much better algorithm for digital volume implementation.
Almost smashed my mechanical keyboard running to the Naim Unity Atom to pull the plug. Would have blown my £1000 speakers for sure.
Recorded it on YouTube:
Note I pressed + to turn up the volume and it just kept on going. Ran and pulled the plug to the Atom so playback stopped. Took the video when the Atom was back online so nothing is playing automatically of course.
I did battle with the volume with the mouse but as you can see it has no effect.
The only solution is to close the Roon App on my Windows 10 PC and then Re-open it.
Even if you turn the device/endpoint off - as soon as it’s back online it continues to try to set the volume to 100%. Luckily nothing was playing of course when the endpoint came back online.
I have a Roon logfile if you need developers?
I think you need to put some sort of safeguard in the software…
