Sound Cards Detected but Unable to Hear any Sound

jleid · 2020-10-26 05:29:46

Hello. I've been dealing with this issue repeatedly for quite some time now, which has resulted in me having to reinstall my system many times, thinking that it must have happened due to my own blunders. But I know This hasn't anything to do with my actions any more (that I'm aware of) because as I've monitored everything after my current installation, it is still happening.

Without fail, my audio will be working fine until a certain reboot occurs. Then it acts like it can't establish a connection to any sound card or drivers. I have been wanting to build this system for audio production, using alsa with jack audio, and no pulseaudio. I installed Arch without pulse this time specifically, and I had audio. I set up Jack, and prepare everything for real-time permissions as instructed through the Jack audio website. Everything should be set up properly, because it worked at first, then, like I said, after a reboot some time later, suddenly I have no audio connectivity.

I have checked through aplay and everything else I've seen online to see that it is detecting my soundcards, which it is. I had to add the alsa-base.conf to /etc/modprob.d/ and list my default cards so there is no confusion. I've searched the internet for solutions to this issue, only finding that most others having this problem are having the issue because their system doesn't detect the sound card, which mine does.. so why can't I get any sound to work, and what the heck happened? And why does this happen EVERY time, that eventually it just dies?

I have no other choice but to ask for help here and see if I can debug this with the help from someone. Please help me understand what's going on and how to understand my system better. I've tried to do everything correctly but something is obviosly not configured correctly, or something is getting changed that I'm not aware of, and I want to know what is is and how to keep it from happening. Thank you

Can you provide logs and hardware information between [ code ] tags?
It's hard to guess what could be wrong without actual™ information.

This sounds like whatever you've attempted to set up is set up too eagerly and steals access to the cards before your normal session invokes properly.

As mentioned this needs more information on what you are actually attempting to be doing and what you are actually doing to configure this.

How do you log in/how do you start your session? By which means do you invoke the sound setup (... and when? did you configure jack to start during boot, how where?)

FWIW regarding real-time permssions and the jack website, it should be sufficient to install the realtime-privileges package and adding your user to the realtime group, and you should probably primarily folllow https://wiki.archlinux.org/index.php/JA … ection_Kit instead of the jack website as there might be different assumptions at play (... we specifically and intentionally avoid the audio group as that has many more implications than what you usually want...)

Maybe during such a faulty reboot post

sudo fuser -v /dev/snd/*
aplay -l
loginctl show-session $XDG_SESSION_ID
