No sound

[j529]

RPi 3b+

I spent a lot of time getting things working a few months ago. Finally got around to building a cool custom case for it and have no audio now. I'm trying to play through headphone jack. Have tried with and without running raspi-config. Have tried running sudo and as pi. Have tried different skins. Tried adding a asound.conf file as one user suggested here. I do not have any kind of soundcard and am using the 7" touchscreen

oxmplayer is what I used to test that the speaker is working through headphones, no problem. Not sure where else to turn on this one.

Previously, I had some problems with running it from .bashrc, but if I raspi-config headphones and ran from command line, all was well. Now, I can't seem to get any audio to output at this point.

If your RPi is updated maybe is an alsa issue. I had a similar problem that i fixed with the following solution (or workaround i dont know), if interest to anyone:

Here’s the step-by-step solution:

In the command line type:

sudo touch ~/.alsoftrc
sudo nano ~/.alsoftrc

Will open a file, paste this, save, exit:

[alsa]
mmap = false

then type:

sudo cp ~/.alsoftrc /etc/openal/alsoft.conf
sudo reboot

Thanks my friend... tried this, but didn't work out. Clearly Fruitbox and the audio library its using is doing something different than anything else on the system. I'm guessing that's it's a configuration file somewhere, but not great documentation out there... everything else that uses audio works fine...

Try then:

edit cmdline.txt

sudo /boot/cmdline.txt and add:

snd_bcm2835.enable_hdmi=1 snd_bcm2835.enable_headphones=1 snd_bcm2835.enable_compat_alsa=1 save, exit and reboot
