i assembled a new PC based on a AM4 Platform. The Mainboard provides a Realtek ALC892 Codec for audio.
Sometimes the sound gets very distorted (crackling noises). Since the last boot the problem is persistent.
I attached my headphones using a 3.5mm cable, when attaching the headphones directly the problem does still exist, so this is not the problem. When i attach the headphones to my android device the sound is perfect, so it has to be related to my setup here.
- Ubuntu Version is 16.04.3
- Kernel: 4.10.0-42-generic
I allready checked this related quesion, but that did not work.
The sound is like someone is constantly twisting the cable. It is extremely annoying :-(
Did not find any solution so far, the situation is unchanged (kernel @ 4.13.0-32-generic).
I noticed, that the crackling starts about 1 hour after i booted and persists for about 15 minutes. It will not happen multiple times in one work-day - only once. Rebooting helps, but i cant reboot all the time...
Very strange: Today the same problem occured on a different machine. This machine has a Creative Soundblaster SB0730 soundcard connected via PCI because the integrated audio is broken. Everything worked perfectly until today - when suddenly the sound began to freak out.
Its a dualboot setup, so i booted into windows to see if the soundcard causes the crackling but windows plays all sounds perfectly.
This problem is really really weird. Both systems are AMD-based, this system is a AM3+ Platform with a AMD FX-8320, Mainboard = ASUS M5A97 LE R2.0.
Same Ubuntu version, same Kernel, so it might be connected...
No change, but it seems to happen less often now Kernel: 4.13.0-43-generic
