[SOLVED] RazPi 4 sound issue

business_kid · 04-16-2022, 10:58 AM

RazPi on Slarm64-15.0. Yesterday I had sound.

Today, it's weird. aplay plays wav files, but vlc, chromium are silent. Everything looks good in pavucontrol, alsa is ok, but no noise. Restarting services

Alsa complains about failing to import hw configuration use cases
/etc/rc.d/rc.pulseaudio returns "command not found." But it's there!

Any ideas?

/etc/rc.d/rc.pulseaudio is disabled.
do

Code:

chmod 755 /etc/rc.d/rc.pulseaudio
cp /etc/asound.conf.new /etc/asound.conf
/etc/rc.d/rc.alsa stop
/etc/rc.d/rc.pulseaudio start

Hi, & thanks for the prompt reply.

I tried that, but no joy. I dislike pulseaudio because it's so difficult to diagnose.

I have Covid atm, so the only thing that could have gone wrong is a rough power down. I will try a disk check. Other ideas welcome

try to run one application using sound output, you may need to configure alsa dmixer.
vlc, chromium compilation to current.
you can also check ldd executable files.

Look, this was all working the day before yesterday - I shouldn't need to change stuff on the SSD, I have

sda1 = /boot
sda2 = root (/)
sda3 = /home

I'm up today. The disk check revealed a load of orphaned inodes on sda2, but of course there's no way of telling where they were.

So I've restored a backup of the sda2 partition on my pc and will try it later. I'll just mark this solved after I try it or post again.

I restored a backup from when everything was perfect, but still no sound. But if I use an sdcard instead of disk drive, I have sound

This should not be happening, but it is

check the kernel you are using, is it from the distribution or from images_build_kit (image)

business_kid · 04-19-2022, 05:13 AM

The kernel is from the distribution.

The probable cause of this is a rough power down. I found a bundle or orphaned inodes. So I deleted /boot and / (but not /home), remade the filesystems, and am restoring again. We'll see if THAT sorts it.

Right, I did all that, and I have a little progress, but no sound.

In pavucontrol, there's a sort of 'VU Meter' on the "Playback" & "Output Devices" tabs. Now I have sound on the "Playback" tab, but not the "Output Devices." Is that in the least way diagnostic?

business_kid · 04-24-2022, 01:59 PM

I FINALLY got this.

I had vu displays in pavucontrol/playback, but none in output devices. I was trawling through that, and discovered a 3rd icon to the left of the lock symbol. I clicked on it, and sound was restored. It was some sort of mute thing. How it got there I don't know.
