[solved] No sound dummy output

Hi,

i have no system sound on integrated sound card. HDMI and DP and USB-C should work. Preferences shows only dummy output if external display with sound is not connected.
This happend after i edited /etc/pulse/default.pa an added the line

load-module module-alsa-source device=hw:2,0

because my microphone did not work. So now my micro works but not my intern soundcard.
Please help me.

regards,
Arthur

Re: [solved] No sound dummy output

Remove that manual alsa source load, restart pulseaudio and post

aplay -l
arecord -l

Re: [solved] No sound dummy output

That's still with the manual module load, I'd be interested to know what the default state is without explicitly loading the source manually.

Re: [solved] No sound dummy output

Because you appear to have masked it at some point for some reason, so what are you actually running:

ps aux | grep pulseaudio
sudo fuser -v /dev/snd/*

Re: [solved] No sound dummy output

mhm, this all sounds kind of weird.

pulseaudio -k
pulseaudio -vvvvv

should be a lot of output can you post that?

Re: [solved] No sound dummy output

We need that output from a not running pulseaudio, so you can go ahead and mask it again and run these two commands

Re: [solved] No sound dummy output

E: [pulseaudio] module-udev-detect.c: Failed to parse module arguments
E: [pulseaudio] module.c: Failed to load module "module-udev-detect" (argument: "#tsched=0"): initialization failed.

You can't comment module parameters like that, remove the #tsched=0 from module-udev-detect.so line and repost the resulting output. Maybe also just post that config file because you might be doing more misguided things.

Re: [solved] No sound dummy output

ok, i don't know why but now it works.
Did the parameter tsched=0 at the end of load-module module-udev-detect cause the problem? What does tsched=0?
I wanted to fix an sound delay problem like: https://lesterlo.wordpress.com/category/ubuntu/

The micro is very quiet although volume is max. Is there anything to do against that?

Re: [solved] No sound dummy output

tsched=0 if you had it as tsched=0 rather than #tsched=0 would not have caused this problem. You gave an invalid parameter to udev-detect and udev-detect is the module responsible for autodetecting your audio cards.

tsched=0 disables timer based scheduling. The only time it is really necessary if you have a broken audio driver, which of the top of my head are only some specific creative chipsets. For the vast majority of use cases you don't want to set it and will get better latency and delay guarantees.

For the quiet mic there might be some mic boost you can enable check alsamixer -c1 or -c2 depending on which mic you are actually using now.

Re: [solved] No sound dummy output

preferences only show me one micro. This one has no mic boost. alsamixer -c2 has an mic boost. but is not shown in preferences. How can i enable that micro?
At last i want to thank you very much for your help!

Re: [solved] No sound dummy output

That is a control that isn't really exposed to pulse clients, you can change/increase that in alsamixer and just use that as a baseline.
