Hi there! I ran the script and it is working fantastic! Thankyou. However I was wondering if is there a way to control/adjust the volume while in ES. If not, if is there a way to pre-configure the volume level in the script. Great work!

@mtib Emulationstation has an audio volume knob which allows you to change the volume - doesn't it work for the background music ?
Alternatively you can add the --gain parameter to the mpg123 to set the volume (0-100):

# to set the volume to 40%
mpg123 --gain 40 [..other parameters following..]

@mitu @mtib You can try out mpg123 -f parameter.... The gain is a deprecated function. But I've to admit never used the gain function ;)

mpg123 -f #####

32768 - Volume 100%
29484 - Volume 90% 
26208 - Volume 80% 
22932 - Volume 70% 
19656 - Volume 60%
16380 - Volume 50%
13104 - Volume 40%
9828 - Volume 30%
6552 - Volume 20%
3276 - Volume 10%

To mention .... in mpg321 the --gain option is documentated ;)

Thanks!

Right, but then will affect the UI fx level as well.

Ok I am missing something, when I type this command in Putty, I get:

# pi@retropie:~ $ mpg123 -f 32768

You made some mistake in program usage... let me briefly remind you:

You need to append the rest of the parameters - the filename/playlist for mpg321. You should add the -f <volume> to the initial command used in the script.

mtib

I really appreciate the help, but sorry, noob here. Should I type this?

# mpg321 /home/pi/radio/list.txt -f <32768>

mitu

@mtib Can you post the autostart.sh file that you modified to add the music script ?

Sure.

while pgrep omxplayer >/dev/null; do sleep 1; done
(sleep 10; [[ -f /home/pi/radio/list.txt ]] &&  vlc -I oldrc --rc-fake-tty --rc-unix /tmp/radio.sock -Zq --no-video /home/pi/radio/list.txt >/dev/null 2>&1) &
emulationstation --no-splash #auto

mitu

So it seems vlc has no ~~direct~~ usable CLI option to pass the volume, however it's possible to use gain to alter the sound output. The parameter works by multiplying the current volume % with the value. Assuming a 100% volume, then

--gain=1 would make the volume be 100%
--gain=2 would amplify the volume to 200%
--gain=0.3 would make the volume at 30%, etc.

So modify the command line that starts vlc in your file, and instead of

(sleep 10; [[ -f /home/pi/radio/list.txt ]] &&  vlc -I oldrc --rc-fake-tty --rc-unix /tmp/radio.sock -Zq --no-video /home/pi/radio/list.txt >/dev/null 2>&1) &

add a --gain=<X> parameter with the <X> to your liking (the line below has --gain=1):

(sleep 10; [[ -f /home/pi/radio/list.txt ]] &&  vlc --gain=1 -I oldrc --rc-fake-tty --rc-unix /tmp/radio.sock -Zq --no-video /home/pi/radio/list.txt >/dev/null 2>&1) &

@mitu Thankyou so much!!! It works.

Hi, it´s me again :)

I disabled the initial text in Emulation Station with this command:

emulationstation --no-splash #auto

So this way:

emulationstation --no-splash #auto

while pgrep omxplayer >/dev/null; do sleep 1; done
(sleep 10; [[ -f /home/pi/radio/list.txt ]] &&  vlc --gain=0.5 -I oldrc --rc-fake-tty --rc-unix /tmp/radio.sock -Zq --no-video /home/pi/radio/list.txt >/dev/null 2>&1) &

I have no initial text and also no radio

But when I put on the last line:

while pgrep omxplayer >/dev/null; do sleep 1; done
(sleep 10; [[ -f /home/pi/radio/list.txt ]] &&  vlc --gain=0.5 -I oldrc --rc-fake-tty --rc-unix /tmp/radio.sock -Zq --no-video /home/pi/radio/list.txt >/dev/null 2>&1) &

emulationstation --no-splash #auto

I have radio but the initial text persists. Is there a solution for this?

The parameter is correct (--no-splash) and the emulationstation command should always be last. If you run the command from the command line (after exiting Emulationstation), does the splash show up ?

It doesn`t.

mitu

@mtib So the command is correct, are you sure you're typing it right in the file ?

I just copied and pasted, it is the same command. Anyhow the radio script is disabling it. When I change the order it works nomarly.
