Sorry to here yoour troubles. Your welcome.

Are you using wireplumber? Is the sound server up?

the tree package just prints out a directory tree...
tree

~/build $ tree -dl -L 7

Thanks for joining.

Yes, I have the WP and for a moment it showed the DAC both as physical device and on the output node as default, but there was still no sound; and shortly afterwards the DAC disappeared.

All my audio players crash with the error message "Internal data stream error"

I tried the command

Code:

~/build $ tree -dl -L 7

, but get "No such file or directory"

Just switched from kernel 6.2.0-37 to 5.15.0-89-generic, and the DAC now shows up everywhere - in WP, PA Volume control and Sound - but still no sound...; same error message (Internal data stream error) from the music player (Clementine), bot it and the Rhythmbox effectively don´t run, but automatically Stop or freeze/crash

wind-wind · 12-03-2023, 12:49 PM

Installed the SMPlayer and - again - no sound via the DAC, but bellow is the crash log, seems to me at the end there is some pertinent info

Wide view forum page...

When I switched over to pipewire and wireplumber I ditched pulseaudio, as much as possible.

I think you have a conflict between sound servers,
one of them needs to be switched off (sysinit, startup-services) and/or firmware updates.

This post may help you.

After installing PW I deleted PA and only the former is active in my system thus, I suppose, no such conflict is the cause of my issue.

Btw, I noticed that my forum display is ultra wide, but cannot figure out how to make it to fit the browser window

When I entered alsaplayer in terminal I got the following:

Code:

Seems some stuff is missing. What would you suggest?

Thank you.

From Software Manager I installed a graphical desktop front end of alsamixer (QasMixer) and when I select the sound card for the DAC (2: Micromega MyDAC, USB Mixer) I get the following details:

Mixer device couldn't be opened
Function: snd_mixer_load
Address: hw:CARD=2
Error: Invalid argument

When alsamixer is entered in terminal and I try to select the DAC I get the same response:

Code:

flo@florentis:~$ alsamixer
cannot load mixer controls: Invalid argument

I guess this is the problem. Any ideas what to do??

Thanks in advance

Hi, it seems you have some underlying issues that I hope you can install your way back.

The ultra-wide page is from #21 (mvp config or something) not usefull you may delete that post, imo.

How did you delete pulseaudio?

Check if alsa, oss, pipewire and wireplumber are installed, if possible (re-)install them and any dependents again.

I still use plasma-pa, pulseaudio volume controls for KDE5 Plasma (desktop).
And many people, I've read still use pavucontrol with pipewire and wireplumber.

you will still need pulseaudio (libpulse.so) for some programs that may be hardcoded and/or hardlinked.

Then, please show how you know what services have started. like pulseaudio.

Can you search for libpulse with
"locate libpulse"

Code:

/usr/lib/i386-linux-gnu/libpulse-simple.so.0
/usr/lib/i386-linux-gnu/libpulse-simple.so.0.1.1
/usr/lib/i386-linux-gnu/libpulse.so.0
/usr/lib/i386-linux-gnu/libpulse.so.0.24.2
/usr/lib/i386-linux-gnu/pulseaudio/libpulsecommon-16.1.so
/usr/lib/x86_64-linux-gnu/libpulse-mainloop-glib.so.0
/usr/lib/x86_64-linux-gnu/libpulse-mainloop-glib.so.0.0.6
/usr/lib/x86_64-linux-gnu/libpulse-simple.so.0

/usr/lib/x86_64-linux-gnu/ao/plugins-4/libpulse.so
/usr/lib/x86_64-linux-gnu/pulseaudio/libpulsecommon-16.1.so
/usr/lib/x86_64-linux-gnu/pulseaudio/libpulsedsp.so
/usr/lib/x86_64-linux-gnu/vlc/plugins/access/libpulsesrc_plugin.so
/usr/lib/x86_64-linux-gnu/vlc/plugins/audio_output/libpulse_plugin.so
/usr/lib/x86_64-linux-gnu/vlc/plugins/services_discovery/libpulselist_plugin.so

All the best.
