Starting from cable settings:
remote_opts="-R"
local_opts="-R -S"
remote_driver_opts="--nperiods 2 --period 512"
local_driver_opts="-l1"
local_driver_opts: -l
- values >> 1 (e.g. 10) lead to distortions. Best setting seems to be 1.
remote_driver_opts: --period
- small (128) -> distortions
- large (4096)
- either good sound for some minutes, but then broken connection
- distortions right away
remote_driver_opts: --nperiods
- large (50) -> no effect
remote_opts, local_opts
-r(no realtime) for both instead of-R/-R -S(realtime and sync) -> no effect observed but that has to be better, TODO: check again when many other Wifis are active
