Adjust Volume

swegs

How can I lower the volume. I'm using the Picade Maxi and the volume is way too loud.

mholgatem

in command line type:

amixer controls

You should get something that looks like this:
numid=3,iface=MIXER,name='PCM Playback Route'
numid=2,iface=MIXER,name='PCM Playback Switch'
numid=1,iface=MIXER,name='PCM Playback Volume'

find the numid for volume and type as follows (substitute the correct numid where necessary and set percentage of volume to what you want):

amixer cset numid=3 50%

Excellent, thank you. I got as far as the amixer controls and couldn't figure out how to adjust it.

Next question, if I try to load a rom and it fails and kicks me to the terminal, the only way I know how to get back the to the launch screen is to do a "sudo reboot". Is there a command to load the game launch screen again without having to do that?

I believe that you type

sudo python ./launchmenu.py

I'm not 100% sure, since I moved back to V.7.10. But I think that's what it was.

On pimame 0.8 from the pimame/pimame-menu/ folder, type python ./launchmenu.py

Thanks for the confirmation @ssilver2k2!

Guys, I'm using the latest beta of PiPlay, and I'm trying to set the volume level for my piCade. For a while I couldn't fix the sound to come out of the speakers, rather than on the HDMI, but I fixed that by editing config.txt and adding

amixer cset numid=1 3

Then I've added a line to set the volume of:

amixer cset numid=3 -4918

When I check the volume setting using amixer cget numid=3, it confirms this value is set, and yet, when I access one of the roms (kung-fu master), it just seems to set the original volume again, which is way too loud.

If I go back to the command line and use alsamixer to reduce the volume and restart, the sound is the right level. I'd just like the volume level to work straight from the config. Is there anything I can do to force the value - or is this maybe a beta issue?

Thanks,
Rich

I think that this may be more of a raspberry-pi/alsa deal, rather than pimame. I posted this article somewhere else in this discussion, but if you haven't checked it out, you should. There is a section on saving the alsa state that may help you. You may also want to download alsa-utils, that may help too (sudo apt-get install alsa-utils)

Howdy, Stranger!
