Public bug reported:

This seems to be a common problem on XMG Clevo W230SS there is no output
on the headphone jack after suspend. The headphones are detected and the
speakers are muted, but there is no output to the headphones. Init-
headphones does not help:

sudo init-headphone 
WARNING:root:Kernel parameter is missing: acpi_enforce_resources=lax
WARNING:root:Module is not loaded: i2c_dev
ERROR:root:Can't find i2c bus
ERROR:root:Operation failed

Any workaround beside reboot?
