Hi,
I installed Tumbleweed and i have a sound problem… only have sound when computer is charging. If i disconnected it from charging, i have no sound.
No problem with headphone jack or connected to HDMI.
Any idea?

Please tell us a bit more about your audio hardware. Run the following command and report back…

inxi -Aa

Assuming that snd_hda_intel module is responsible for your sound hardware, you can check power saving parameters like this (just in case that is impacting somehow)…

cat /sys/module/snd_hda_intel/parameters/power_save_controller
cat /sys/module/snd_hda_intel/parameters/power_save

Then we may be able to advise further.

You could try inhibiting sound power management with respect to this driver.

FWIW, some laptop users install ‘tlp’ (power management utility for laptops).
