I've only recently begun working with Raspberry Pi, and decided to start with what seemed like a relatively simple project in the Pirate Radio (found here), but I have been unable to make it work properly. I am able to run PiFM from the terminal with ease, by typing in the following:
sudo /usr/bin/mpg123 -4 -s -Z /home/pi/Music/* | sudo /home/pi/pifm/pifm - 106.1
However, when I try to make PiFM run at system startup, it always gives me a black screen while playing the first second of a song on repeat infinitely. Originally I created the bash script as described in the Pirate Radio tutorial linked above, by making the following script,
#!/bin/bash # /etc/init.d/pirateRadio.sh ### BEGIN INIT INFO # Provides: pirateRadio.sh # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Runs radio # Description: Runs my radio. ### END INIT INFO case "$1" in start) echo "StARRRRRRRting Pirate Radio" sudo /usr/bin/mpg123 -4 -s -Z /home/pi/Music/* | sudo /home/pi/pifm/pifm - 106.1 ;; stop) echo "Stopping Pirate Radio" killall pifm ;; *) echo "Usage: /etc/init.d/pirateRadio.sh start|stop" exit 1 ;; esac exit 0
So, this did not work, as I described above. Upon looking it up to see if there were any solutions online, I found this, so I tried the solution found in there. However, this did not work. For reference, I put the following into my
#!/bin/bash # rc.local export PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/sbin:/usr/bin ( exec &>> /var/log/my_rc_local.log mpg123 -4 -s -Z /home/pi/Music/* | /home/pi/pifm/pifm - 106.1 ) & exit 0
Again, upon booting up my Pi, it would give me a black screen and the first second of a song on repeat. So, I am stuck, and do not know what to do to fix my little FM transmitter. I would appreciate any and all help I may receive, thank you.
