Audio on plays on HDMI, but not headphone jack [RPi 3]

[jeffreylin]

What the title says - VCV Rack works fine on my RasPi 3, but only on HDMI, and not with the headphone jack.

I know it's not the headphone jack itself, since the headphone jack plays sound fine w/ stock Raspbian.

Here's my aplay -l in case it helps:

sonaremin@sonaremin:~$ aplay -l

Thanks so much for all the work you've done on Sonaremin so far - looks amazing and hoping to get it to work. Let me know if I can print any other output to help debug.

Actually this is sort of incorrect - If I run my RasPi 3 headless and don't plug in a HDMI monitor, then headphone sound does work. However, plugging in the HDMI cable afterwards doesn't give me any display signal so I can't see the GUI. =/

Will look into some way to disable HDMI sound all together.

hi @jeffreylin ,

thanks for reporting this - i think itested it with a hdmi monitor without audio and i think there it worked. please let me know if you find a way to send the audio to the proper output.

Edit config.txt on root of boot part.

Add:

hdmi_ignore_edid_audio=1 audio_pwm_mode=2

The 2nd line is optional - removes noise/hiss.

Reboot. Done.
