8.2.4 MR audio issue

    Hello, I'm having this issue since I updated to the newest version 8.2.4 MR, the problem is that the audio has a crackling noise when I use tvheadend, I have the RPI 3 (not the new one), If I open the channel from the network with VLC I don't notice any crackling noise.

    I copied an image of the previous version and there is no noise but when I update to the new version (8.2.4 MR) the noise is back so I'm sure it's a problem with the newest update of Libreelec.

    I use the 3.5 jack with the analog "audio output device" setting.

    Hello,

    Crackling sound here too on a raspberry 3B+.

    I2s output.

    audio_pwm_mode=2 didn't fix.

    Reducing audio level in kodi by 2 steps make it disappear but a better fix is welcome ;)

    Edit : still slight clipping distorsion with 2 steps reduction. 3 steps is safer with loud tracks

    Do you get the same issue when using the newer firmware on 8.2.3 builds?

    Do you have Resample Qualtiy set to "GPU accelerated" in Settings->System->Audio (settings level must be advanced or expert to see/change that)?

    Does it go away when changing Resampling Quality to Medium or High?

    so long,

    I tried audio_pwm_mode=2 and it didn't work, the "Resample Qualtiy" is medium but no matter what I set it to the problem is not solved.

    Something that I noticed is that if I change the "Audio output device" from "analogue" to "hdmi" or "analogue and hdmi" while playing a channel the audio gets distorted, it's like a low pitch so everything has a grave sound. The only way I know to fix the pitch issue is to reboot libreelec.

    Resample Quality is set to Medium

    But there is no resampling as 'Audio output configuration' is set to 'Best match'

    I may try a 8.2.3 build with newer firmware but it will take a few time (I need to rebuild from sources to use a custom overlay...)

    +1 , 8.2.4 has been really problematic for me on RPI2. I experienced system freezes during playback which only reboot fixed. The only workaround that seem to fix this is rolling back to 8.2.3

    Disabling deinterlace fixes it, Bob (half) is better, Bob is the worse (and I think that "Auto" selects this one), the two Advanced options also fix the issue.
