adding audio_pwm_mode=1 solved the crackling and popping, but all sound (both YouTube and the clicking sound in the GUI) is now really muffled and there is an "overlay" of static noise.
Is that to be expected of that setting?
I am still not convinced it is simply limited by the audio jack.
a) it worked with no issue on Matrix 18 and
b) it works in all other plugins, only youtube is causing the crackling
the RPi4 cannot HW decode when playing netflix. So HW decoding 1080P H264 may be at it's limits.
CPU/GPU loads are at 60-70% or below while watching netflix @1080p. Also I don't think the Pi is limiting as one episode is fine, while the next one buffers repeatedly. I doubt the quality/stress while decoding differs that much from one episode to the other, right?
I would advise you not to use the headphone jack. It is known that it has poor audio quality.
Thank you, but like I said the audio is decent in other applications.
Crackling audio is a known issue with H264 hardware decoding, adding audio_pwm_mode=1 to config.txt will fix that but result in lower audio quality.

I will try that tonight and give feedback for others that might find this. Thank you!

Hello,
I am getting crackling static sounds while watching YouTube Videos on my Pi4 (4GB), Libreelec 95.3.
It only occurs in YouTube, while the audio is fine for offline mp3s or other streaming options.
This started occuring once I upgraded to Matrix 19 and still happened for the last 3 updates I installed.
Any advise on smart settings to try?
Thank you,
Beda
Hello,
I am running CastagnaIT's Netflix Add-On on a Rasperry Pi 4 (4GB) in Libreelec 95.3, but I get randomly occuring buffering while streaming in 1080p.
The Pi is connected to the router via cable and we have a 50 Mbit/s connection. Speedtests on the pi itself show atleast 45 Mbit/s at all times.
The same movie or show runs fine on 2 Android devices, a laptop and a PC.
There is nothing else taking away connection speed when the buffering occurs and it is not correlating to a certain time of the day.
My ISP is not throttling netflix either.
The problem occurs either as a "real" buffer (loading circle for a couple of seconds) or the audio and video stream get out of sync until the loading appears. Pausing the show/movie and waiting for several minutes does not change anything. Also, one show or episode runs fine while another makes problems throughout the stream.
Do you have any advise for me?
thank you,
Beda
