Weird Reverb Decaying Echo

Under Cinnamon I get a decaying echo hi hat when playing sounds over line in monitor speakers. Present for most sounds but not over stereo out. Recently appeared, sadly still present with 18.3.

In a terminal:

Code: Select all

sudo nano -w /etc/pulse/default.pa


Look for this line:

Code: Select all

load-module module-udev-detect


Add tsched=0 to the end of the line, like this:

Code: Select all

load-module module-udev-detect tsched=0


ctrl-o, enter to save, then ctrl-x to exit.

Reboot.

Thank you for your response. I have;

Code: Select all

load-module module-udev-detect .else


Editing with your code produces no sound, editing without ".else" produces no sound, is there another option?

It shouldn't look like that. It should look like this:

Code: Select all

### Automatically load driver modules depending on the hardware available
.ifexists module-udev-detect.so
load-module module-udev-detect
.else
### Use the static hardware detection module (for systems that lack udev support)
load-module module-detect
.endif


I included the lines around it for context.

You are correct, however original edit proposed results in no sound.

Fresh install resurrected sound but clipping still present any volume, got a good three years outa Mint install since 17.3, pretty good run. All OS suffer decay/degradation it would seem...

What is -w switch? Merely editing file under 18.3 results in no sound. Purging ALSA & PulseAudio & reinstalling has no effect.

W, --wordbounds

-w switch kills sound when edit file wth Nano, at least with latest Pulse Audio update. So when 18.2 was upgraded, sound failed, or OTB with 18.3. Was this malicious? I don’t think so? Always Clonezilla peeps.
