Bug Description
Binary package hint: pulseaudio
Hi,
just upgraded to current Karmic beta. All went fine and well, but I have one issueabout the volume control - as it's working now it's almost dangerous.
When I adjust the volume slider I can max out my laptop speakers at about 15%, any higher and they are about to blow. When using a headset I can't go over 9% before the sound gets dangerously loud. When using the volume buttons on my laptop I can start at 0%, then click two times until the volume becomes so loud (12%) I don't dare go any further when wearing a headset...In Jaunty I had a much more fine-grained control.
After inspecting how the new volume control works, I see that it adjusts both the master volume and the PCM according to some algorithm. While in concept I understand this is smart in order to keep noise down, it works really terrible in my case. Imagine having a computer that if someone (or something!) sets the volume to anything above 20% and your speakers (and hearing) stand a good chance to blow.
Laptop:
Fujitsu Siemens Si1520.
lspci -v attached.

- Volume control is "dangerous" when setting volume level + Another sound problem (volume and balance) |
This is ultimately a linux issue, so please add a linux task to this bug.
In the meantime, you can ignore one or more elements in any stanzas. pulseaudio/ alsa-mixer/ paths/analog- output. conf.common. You
See [Element PCM], for example, in
/usr/share/
just need to change volume = merge to volume = ignore.
