Ubuntu sound volume is 40% lower than in Windows
- by ncomx
I have 2x 2.1 speakers connected to the computer where I have Ubuntu 12.04 installed. On the software side I've set all the volume controls to 100% with the alsamixer program.
The speakers have their own volume control, maintaining those at the same level, and switching between Ubuntu and Windows (XP and 7), on windows the output volume is at least 40% higher, even when having the windows volume control at 50% (without touching the speakers volume control) it's still much higher than the sound on Ubuntu.
Why can this be happening?
Are there some alternative sound drivers (other than the default ones) I could test to see if it makes a difference?
some info about the card:
root:$ cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xfbff4000 irq 55
1 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfbcfc000 irq 56
root:$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)
02:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Cayman/Antilles HDMI Audio [Radeon HD 6900 Series]
I think the one i am using is the Intel one, the other seems to be from the vga card which is an ati radeon 6950.
Running gstreamer-properties and switching between alsa, oss, ossv4 and pulseaudio doesn't seem to make any difference.
