I have a Thinkpad T530 and the max volume on Linux (Xubuntu 16.04) is quite low compared to Windows on the same macine.
You can push the volume above 100% with the volume control UI, but it resets to 100% whenever I change volume with the keyboard keys, so I'm looking for a better solution. I'd also rather not use external speakers (its a laptop), so I'm trying to do this with software.
Here's what I've tried so far:
pactl set-sink-volume alsa_output.pci-0000_00_1b.0.analog-stereo 150%- also resets volume when I touch the keyboard controls. No dice.
Checked mixer levels in
alsamixer. Everything relevant (Master/Speakers/PCM) is already at 100%.
Created an ALSA softvol control in
/etc/asound.conf, as described here and here. I got the control to appear in alsamixer, but it has no effect on volume. However, it does work if I kill the pulseaudio daemon and just use ALSA.
Right now I'm attempting to modify my
asound.conf to work with PulseAudio, but think that I may be out of my depth here.
It doesn't seem like I can use a
pulse type PCM device as a slave in ALSA to get the softvol amp to work, and I have no idea how to route the default audio device to it when PulseAudio is running anyways.
Any help is appreciated, thank you.
