[Dell System Inspiron 15 7000 Series 7537, Realtek ALC3223, Speaker, Internal] Underruns, dropouts or crackling sound

[Seamus McDonell]

The audio constantly clicks overtop of what is played. This began occurring after fixing a previous bug where audio would not play through speakers. All that was done fixing this bug was uninstall and reinstall pulseaudio and the alsa-base. Occasionally the clicks will be replaced by random noise.

Status changed to 'Confirmed' because the bug affects multiple users.

[Alessandro Zucca (alessandro-zucca01)]

Confirmed also on my machine, lowering the PCM volume seems to be the only temporary fix to make it bearable.

[Andrés Arriagada Hazard (andres-hazard)]

Can somebody explain the solution to get audio on this laptop.
Thaanks!!

[Francesco Pontillo (francescopontillo)]

I can confirm this on my Del 7537, I can't seem to find a solution. Did anyone manage to do that?
