Scratchy cracckles with sound..

Hi guys, running Tumbleweed here. Sound has for a while now been very bad with scratchy crackly noise, I hoped that TW updates would “cure” it. For starters, here is ALSA script results… ideas? FWIW, I can boot to MSWin (yuk) and sound is good in Win10…

Your reported audio hardware…

!!PCI Soundcards installed in the system

00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] SBx00 Azalia (Intel HDA) (rev 40)
01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde/Pitcairn HDMI Audio [Radeon HD 7700/7800 Series]

I don’t have a definitive answer here (I don’t have that hardware), but this might be helpful…
In particular

Glitches, skips or crackling

The newer implementation of the PulseAudio sound server uses timer-based audio scheduling instead of the traditional, interrupt-driven approach.

Timer-based scheduling may expose issues in some ALSA drivers. On the other hand, other drivers might be glitchy without it on, so check to see what works on your system.

To turn timer-based scheduling off add tsched=0 in /etc/pulse/

Another similar thread (same SB hardware)…


Thank you @Deano, I have tried this, and first test it seems to work!

That’s a good sign. Let us know how it goes in the longer term.
