Subject: amixer decrease volume fails when volume is 100 and increment is 1 or 2
Date: Sun, 14 Dec 2025 05:45:41 +0100 (CET)	[thread overview]
Message-ID: <1880fb7626f4cb00-webhooks-bot@alsa-project.org> (raw)

alsa-project/alsa-utils issue #313 was opened from vExcess:

If the volume is at 100%, running either of the following fails to decrease the volume
```
amixer -D pulse sset Master 2%-
amixer -D pulse sset Master 1%-
```

Running `amixer -D pulse sset Master 2%-` outputs
```
Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 65536
  Mono:
  Front Left: Playback 64225 [98%] [on]
  Front Right: Playback 64225 [98%] [on]
```
It looks like it has decreased the volume by 2%, but it actually hasn't. When I run the command repeatedly it stays at 98% and doesn't go lower. But even though amixer says the volume is at 98%, Linux Mint still reports it as 100%.

I'm using alsa-utils 1.2.9-1ubuntu5

```
OS: Linux Mint 22.2 x86_64
Host: 83DD IdeaPad Slim 5 16AHP9
Kernel: 6.11.0-29-generic
```
