I looked into some more things to get this solved.
While the Setting application says my power mode - the one it keeps
getting back too despizte I chose another is "balanced", looking into
the system it tells mie it's on powersafe:
$ cat /sys/devices/system/cpu/*/cpufreq/scaling_governor
powersave
...
(repeated with one line like this for each cpu core i have)
Looking at cpufreq-info, it tells me there is not "balanced" option:
$ /usr/bin/cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpuf...@vger.kernel.org, please.
analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 4294.55 ms.
hardware limits: 800 MHz - 4.80 GHz
available cpufreq governors: performance, powersave
current policy: frequency should be within 800 MHz and 4.80 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency is 4.43 GHz.
So I wonder what the balanced option is about, if it's not reflected on the
system, but despite that the system keeps going back to it.
I read the ubuntu help pages about the power mode, and it says these
options in the setting application should do what they look like.
But I cant confirm this.
It ignores my choices, and reverts back to a setting that doesn't event seem to
be known to the system.

Title:
Power Mode keeps switching back to balanced after performance is
selected manually
Status in gnome-control-center package in Ubuntu:
New
Bug description:
I want my computer to keep running in performance mode.
This worked well with 21.04, but since the upgrade the gnome shell applet tp
switch this has been gone, instead in the setting i can now chose between
performance / balanced and power saver.
When I chose performance, close the settings app, and start doing what
I want (make music with applications for this), I soon start to hear
latency crackles.
I go back to the settings then, and continue to see Power Mode being
switched back to Balanced.
What would I expect:
I would expect after chosing Performance explicitly, it would stay like this.
Especially as long as I dont change the power connection state of the machine
or reboot, but ideally even when these things happen.
But here, it doesn't even stay as selected even though the system is
on a power line, and no reboot. It doesn't even last one minute in the
state I chose it to be.
