System volume slider only works between ~90% and 100% with a USB 2.0 speaker

[Max Waterman]

This is only with my USB 2.0 speaker[1] - with other devices, it works fine and the slider's 0% corresponds to silent and 100% full. With my USB 2.0 speaker, with the 'output' set to 'Analogue Output - USB2.0 Device', it only has an effect between about 90% and 100%.

I took a video of the problem and uploaded it here:

FWIW, the speaker works fine on a Huawei Mate 30 Pro/Android 10.

Thank you for your bug report, does it has the same issue if you use pavucontrol or keus or the top panel control?

[Max Waterman (dwater)]

I had to install 'pavucontrol' and it exhibited the same behaviour, as does the 'top panel control' (if I understand that correctly). I couldn't find 'keus' though.

[Expired for gnome-control-center (Ubuntu) because there has been no activity for 60 days.]

[Max Waterman (dwater)]

Not sure why there has been no activity...it certainly shouldn't be 'expired', in my view.

We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed.

[Max Waterman (dwater)]

Still a problem: Ubuntu 20.04.1 LTS

[Max Waterman (dwater)]

I can't change the status to confirmed. What's the point in instructions that people are prevented from following? Very frustrating.
