No audio from 3.5mm jack on G2 Pi

[charbwin]

I think that confirms what I saw. Hopefully the Homeseer people will incorporate the updated kernal in a future release of HS4.

That helped greatly. Now I know what’s going on. Have a read of this. Maybe Linux kernel 5.14 has fixed this. It’s one thing that a user knows something is wrong. It’s another to tell him what https://github.com/raspberrypi/linux/issues/4108

Could you confirm in Raspberry Pi terms exactly what model and spec the G2 is.

I have run amixer through various routes and changed the audio out to the 3.5mm jack. It doesn't work on the G2, output is HDMI regardless of the setting. I believe this has been confirmed by customer service. It works fine on the older Hometroller system. I can switch between HDMI and the jack on the old Hometroller. The link https://www.google.ie/amp/s/windowsr...working/%3famp seems to lead to a logo only.

Did you read up on the link I posted. Have you fully updated your new G2 with sudo apt update and sudo apt upgrade. I imagine your older HomeTroller had default sound to audio jack while your newer one defaults to hdmi. Easily rectified. https://raspberrypi.stackexchange.co...ugh-3-5mm-jack

Run Alsamixer which will easily allow you to switch between all audio outputs. This really is simple.

The test event I use is the same as yours, with one of my audio wav files. I have played around extensively comparing how the new G2 and my old Hometroller behave. The old unit can play audio from either the HDMI or 3.5mm jack depending on the setting. The new G2 has a bug that only allows HDMI output. Both units run on HS4 but have different operating system versions. I loaded a new HS4 disk image into the old system and it behaves the same as the G2 - no 3.5mm jack output. So somewhere an update to the Raspberry has lost the 3.5mm output capability. I've flagged this to HS support and maybe at some point it will be addressed. So I can live with my old system since I've been able to move it to a 32g SD card. I don't know if it will allow unlimited plug-ins. I'll have to test it. I bought a cheap HDMI audio extractor with a 3.5mm audio jack out. If I connect this to the new G2 I can feed my audio setup as it is. An OK work around. I'll have to be careful to have a disk image of the old system before I do any HS4 updates in case the 3.5mm jack output suddenly goes away in the update.

The PulseAudio PCM plugin that's showing in your transcript isn't installed by default on the "lite" version of the OS that I'm running. I'll see if I can load up the HS4-Pi image to better replicate your environment.

Just to make sure we're on the same page ... what event action are you using to play the audio file? Mine is shown below. I verified that this calls play_audio.sh in the HS root, which simply calls aplay.

Read up on this article to give you an insight to what may be going on with your G2. I’m assuming a G2 is probably an RPI3+ so this simplistic article should point you in the right direction https://www.google.ie/amp/s/windowsr...working/%3famp

The old Hometroller gives this result (set to 3.5mm jack, HS4) but no sound comes out (an event does play sound)


The G2 set up the same way, also has nothing out of the 3.5mm jack

Try

aplay -v /usr/local/HomeSeer/Media/gong.wav

I get

By default, HS uses aplay to play audio files - see play_audio.sh in the HS root folder.

#!/bin/sh
aplay "$1"

Is yours different?

In any event, it seems your new unit has an issue, either software or hardware (software probably being most likely). If you wanted to swap the SD cards you might be able to narrow it down.

I tried this on both the old Hometroller and the new G2 and got this result

aplay /usr/local/HomeSeer/Media/gong.wav
Playing WAVE '/usr/local/HomeSeer/Media/gong.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

Results were the same on both systems.

Both had audio outputs on HDMI but neither had an output on the 3.5mm jack. Note though that the old system does play the same wav file on the jack using a simple event but aplay does not get a jack output. The new G2 does not have a 3.5mm jack output using exactly the same setup and commands either with aplay directly or an event.

Linux filename are case sensitive. Make sure the 'Media' folder name is spelled with a capital M.

Also I've installed HS in /opt/ vs. /usr/local/ that HST uses. So try

aplay /usr/local/HomeSeer/Media/gong.wav

[charbwin]

I tried running aplay /opt/HomeSeer/Media/chime.wavsubstituting "gong.wav" a file in my media folder.
I get an error no such file or directory. When I run an event playing the same wav file however I get the message "playing wave /usr/local/Homeseer/media/gong.wav: signed 16 bit Little Endian , rate 22050". I also get the proper audio out of the HDMI output (from a connected TV). I used raspi-config to change the audio output to the 3.5mm jack and ran the same event. Again I got the same message and the audio worked from the TV. However in no case was there any output from the 3.5mm audio out jack regardless of the system audio out selection. It seems I am getting proper audio in HDMI but the 3.5mm jack appears dead.
