first i wrote
sudo gainroot

then i started the player.
i typed in terminal alsamixer -c0 and turned on FMTX Fuction and pushed esc.

Then i typed /usr/bin/fmtx_client -p 1 with no errors

and then /bin/echo 118 > /sys/class/i2c-adapter/i2c-2/2-0063/power_level
with no errors

after that i typed /opt/lfocus/v4l2-ctl -d /dev/radio0 -f 88.1
This gave me a big list of commands :/

The fm-transmitter icon were visible and the music was playing all the time. Still i didnt get anything out in two radios that i tried. I moved the phone everywhere near the radio.

After that i went back to alsamixer -c0 and there i raised the Line dac to 100.
Still nothing I think my fm transmitter is broken
