Hello, I have a raspberry pi 4 running the latest version of DietPi (v6.31.2). I have it plugged in to my TV through an HDMI cord, and to my speakers through the 3.5mm jack. I would like to force the audio through 3.5mm so that I am able to use shairport-sync and play audio without having to turn on the TV, but I am unable to do so. I have set the audio to force 3.5mm through the use of dietpi-config > audio options > sound card > rip-bcm2835-3.5mm (also see image below), but no sound comes through until I turn on the TV. Is this an issue with shairport-sync that I need to configure, or something else?
I appreciate any help!

Re: Unable to force sound to headphone jack RPI 4
Many thanks for your report.
Did you reboot one time after applying the sound card selection?
Can you paste the output of amixer -c 0 contents (in case after reboot if 3.5mm output still does not work).
And in case try to add hdmi_drive=1 to /boot/config.txt and reboot another time. This forces DVI mode which disables HDMI sound from the other side.

Re: Unable to force sound to headphone jack RPI 4
I did not reboot, but after doing so I have not been able to force 3.5mm. I've added the hdmi_drive=1 line, reboot, and I actually lose all sound coming from the Pi, even when the TV is on.
The contents of amixer -c 0 contents are as follows:
The contents of amixer -c 0 contents are as follows:
Code: Select all
numid=2,iface=MIXER,name='HDMI Playback Switch'
; type=BOOLEAN,access=rw------,values=1
: values=on
numid=1,iface=MIXER,name='HDMI Playback Volume'
; type=INTEGER,access=rw---R--,values=1,min=-10239,max=400,step=0
: values=2
| dBscale-min=-102.39dB,step=0.01dB,mute=1
Re: Unable to force sound to headphone jack RPI 4
Strange. hdmi_drive=1 disables HDMI sound the other way, so it makes sense that you loose all sound then.
What is strange is that numid=2 is not shown in your amixer output as this is what usually switches between 3.5mm, HDMI and auto: https://www.raspberrypi.org/documentati ... -config.md
If you again comment/remove the hdmi_drive line, does amixer -c 0 contents still only show those two switches?
And just to assure: dtparam=audio=on is set in config.txt, right?

Re: Unable to force sound to headphone jack RPI 4
Yes, I get the same results from amixer after uncommenting the hdmi_drive line
The portion in config.txt is also set to on, as well: dtparam=audio=on

Re: Unable to force sound to headphone jack RPI 4
Hmm, probably this needs to be configured differently on RPi4 (although never heard of an 3.5mm issue) or hardware issue?
Btw you can follow any Raspbian/Raspberry Pi OS instructions you find.
Just checked raspi-config and they do the same: https://github.com/RPi-Distro/raspi-con ... 1724-L1737
Ah did we already check if onboard audio is really card 0 or if something else occupied that ID? Please paste the output of:
aplay -l
aplay -L

Meanwhile the issue is known: https://github.com/MichaIng/DietPi/issues/3887
Will be fixed with next release.
If you find time, could you do the following:
I want to assure that all RPi models in such case do not list HDMI as sound "card" anymore but instead the "Headphones" (3.5mm jack) as card 0.

If you find time, could you do the following:
Code: Select all
G_CONFIG_INJECT 'hdmi_drive:0=' `hdmi_drive:0=1` /boot/config.txt # forces DVI mode on HDMI port 0
G_CONFIG_INJECT 'hdmi_drive:1=' `hdmi_drive:1=1` /boot/config.txt # forces DVI mode on HDMI port 1
reboot # Reboot to make changes becoming effective
cat /proc/asound/cards
