No sound using OMXplayer / Arcade Bonnet

[BiZzAr721]

Hello all. I hope everyone has been staying healthy, and getting buy without too much difficulty. I have been using my "quarantine" time to finish a miniature arcade build I have been working on.

I am having issues with video snaps. When I enable OMXplayer, I have video and no sound. Sound is working with OMXplayer off. I have tried changing many settings from /etc/.asound.conf, to /usr/share/alsa/alsa.conf

I had no sound during spash screen but was able to correct that by changing

omxplayer -o both

to

omxplayer -o alsa

in /opt/retropie/supplementary/splashscreen/asplashscreen.sh as referenced in this post.

I can play video previews from command line with

omxplayer -o local /path/to/file/filename.mp4

When

<string name="OMXAudioDev" value="alsa:hw:0,0" />

I do not get a video at all.
When set to local, I get video, but no sound.

Note: I have used these same video's with OMXplayer on a pi without a hat attached.
aplay -L shows

CARD=sndrpihifiberry,DEV=0

I am using a Raspberry Pi 3b+, with a Canakit powersupply, ADAfruit Arcade Bonnet, running the latest Retropie image (v 4.5.1) from a clean install.

Have you used this guide to set up the speaker ? Can you show the output of aplay -Ll in full ?

[BiZzAr721]

@mitu Yes, I did use that guide. I also saw it noted in that guide:
omxplayer does not seem use the I2S interface for audio - only HDMI - so you won't be able to use it

I did not pursue sound through OMX player after that until I came across your post about testing a file using

omxplayer -o alsa

and then proceeded to get splash screen sound back (Thank you BTW)

@BiZzAr721 said in No sound using OMXplayer / Arcade Bonnet:

<string name="OMXAudioDev" value="alsa:hw:0,0" />

If omxplayer -o alsa works, try changing the above to

<string name="OMXAudioDev" value="alsa" />

and see if it makes a difference.

@mitu Wow, well that definitely is a step in the right direction! Sound works, but is extremely low. I had to have the volume nearly all the way up, but then the emulator sound is nearly blowing the speaker.

I only have sound with audio card set as sysdefault, HW, and default. All others will have the volume set to 0 when I go back into sound menu.
Edit : As well as anything other than pcm for Audio Device

I entered alsamixer, but didn't find anything useful there. Is there a way to control OMXplayer volume independant of software volume (or vice versa)?

Temp fix noted: I added audio_volume = -24.0 into retroarch.cfg which for the most part normalizes OMXplayer video snap volume with LibRetro emulators. Since it's a miniature cabinet, I removed non-lr emulators that didn't really need to be on there. The only one I couldn't part with was Daphne (and OpenBOR when I set that back up)!

note2: I altered daphne volume by creating a <gamename>.command file and adding volume variables (along with some other enhancements)
-nocrc -volume_nonvldp 8 -volume_vldp 8 -noissues -nolog -noserversend
Volume is rated 0-64. Daphne command line variables can be found here.
