Hi all,
I’m new to the Mycroft community, but I’ve been playing with Mycroft for a while, so one day I tried to install magic mirror in the picroft image, bought a two-way mirror and a driver for my display, and since I connected the display via HDMI, audio just stopped being outputted from the jack. I’ve tried changing the output in raspiconfig, with amixer cset, and booting without the HDMI cable, and nothing seems to work. The error is system-wide. (Probably this is just some simple noob error.)
Hi Sam, can you check the current pulseaudio settings?
https://mycroft-ai.gitbook.io/docs/using-mycroft-ai/troubleshooting/audio-troubleshooting#pulseaudio-settings
pactl info
should give you the current default sink, then
pactl list sinks short
to see what devices are available and their associated number, finally
pactl set-default-sink 1
to set a new default
let us know if that works
I already tried this before posting and it didn’t worked. Anyway Here Is the information

Did you ever figure this issue out? I’m trying to set up a Pycroft now, and it will only ever play audio out of HDMI
No, I just bought a USB audio card.
After having played with pi’s and hdmi and audio, this is about the only reliable solution I’ve found.
When I first installed Picroft, I also found that sound didn’t play through the audio jack, and I tried both an RPi 3 and 4.
As i had made use of “alsamixer” before, I started that up at command line and made sure that the “Headphones” choice was selected under F6, then made sure the volume setting was turned up with the keyboard up arrow key.
I then used the Linux “aplay” utility (again, command line), and I happened to remember that this path
/usr/share/sounds/alsa
includes WAV files, so I tested the Pi hardware with
aplay ./Front_Center.wav
With that, the powered speaker (a Bose unit) played the file, so I knew there was a configuration that needed changing.
I went to the Mycroft Troubleshooting page and located “Audio Troubleshooting”.
By following the instructions there, I was able to get the 3.5mm audio jack on both of the Pi units to work reliably. I then used the pactl commands to select my USB microphone source and pactl to select the
One thing I was surprised to find explained was the instruction to use
mycroft-config edit system
and find that the system file had extra text from installing the system, text located on both of the lines. I then edited the file to be what is documented:
{
“play_wav_cmdline”: “aplay %1”,
“play_mp3_cmdline”: “mpg123 %1”,
[…]
}
When I saved out the edit, there was also a “Permission denied” error, but I then used sudo to move the file, and rebooted the system.
Audio through the 3.5mm jack has worked fine ever since.
