Hi,
they can not increase. There might be a PCM slider to adjust the volume.

Please, always copy the output _and the command_ you run and don't wrap
lines, when posting output of commands.
When using evolution, then after pasting output change it from "Plain
Text Normal" to "Plain Text Preformatted".
When using Claws paste by using Edit > Special paste > unwrapped.
When using another email thingy, consider to read the manual or simply
add the commands with their outputs as a plain text attachment.
What do the following commands return?
lsmod | grep snd
aplay -l
ls -hAl /etc/modprobe.d/
cat /etc/modprobe.d/alsa-base.conf
cat ~/.asoundrc
Btw. I'm using plain ALSA or the jackd sound server, _not_ the
pulseaudio sound server. By my /etc/modprobe.d/alsa-base.conf the
default card is
card 0: HDSPMx579bcc [RME AIO_579bcc], device 0: RME AIO [RME AIO]
for testing purpose I added ~/.asoundrc, to make
card 3: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
the default. Now I get sound from my HDMI display's speakers.
There's no audio related difference between my Arch Linux and Ubuntu
install, I'm just booted into an Arch Linux session at the moment and
posting the outputs as an example.
