Created attachment 137417 [details] recording of the audio crack through obs SUMMARY STEPS TO REPRODUCE 1. On windows 10, add sound in kdenlive timeline 2. Play OBSERVED RESULT Audio cracks and weird noise (see attachment) EXPECTED RESULT Clean audio. I tried to change various sound settings in playback category of kdenlive settings, no luck so far. This bug makes kdenlive unusable on windows 10 for me. SOFTWARE/OS VERSIONS Windows 10 pro Portable and installed version of kdenlive 20.12.3 KDE 5.79.0 QT 5.15.2 ADDITIONAL INFORMATION Motherboard : ASrock x99 Extreme4 Graphic card : GTX TITAN X Processor : I7-5960X Thanks for your hard work on this software ! Cheers
Thank you for reporting. Does OBS create the clip by hardware acceleration (GPU)? If so can you try generating the clip in OBS by CPU and check if you still have this crackling?
Thanks for getting back, not on my computer this week, i'll take a look after if you want, but definitely positive that it is not Obs fault here, i tried to do some editings in KDE and had this clicks, that's why i reported it... I had this same bug some months ago, but didn't take time to report, i thought maybe it was because of windows platform (it was beta at this time if i recall correctly).
Can you play around with following setting: Settings –> configure Kdenlive -> playback -> choose different audio driver. Settings -> OpenGL backend -> choose different settings. I assume best settings for Win10 would be "Wasapi", "DirectX". Maybe updateting the audio driver of your system could help as well.
I did play with these settings before filling this bug report, after testing all available options without success, it happened to work once, for one session. As soon as Kdenlive was closed, the bug appeared again...
I think I am seeing the same issue - any playback, even scrubbing over even a blank timeline, produces audio crackling. Kdenlive 21.04.1, fresh install MLT 6.26.1 KDE Frameworks 5.82.0 Qt 5.15.2 ASRock X99 Extreme4 NVidia GeForce GTX 1070 Ti Intel Core i7-5820K I notice we both are using the same mobo; its audio is based on RealTek ALC1150. I have driver version 6.0.1.7926. May be a coincidence, but: Voicemeeter and Discord had a similar problem, and they developed a workaround where you give the audiodg.exe process (Windows Audio Device Graph Isolation) High priority and affinity to a single core.
I assume you had a Win10 update lately. The RealTek driver 6.0.1.7926 seems very old (2016?). Try to update the RealTek driver and the Intel graphic card driver. Maybe you can use a standard Windows driver instead of the RealTek driver.
We found another problem lately. Please try the following: - Select the Windows icon in the taskbar, then select the gear to open Windows Settings. - Select System. - Select Sound in the left pane, then select Sound Control Panel under Related Settings in the top-right corner. - Select the advanced tab in the window that pops up. - Set the standard format to 44100 Hz. Try again.

Please try the following: > (...) > - Select Sound in the left pane, then select Sound Control Panel under > Related Settings in the top-right corner. > - Select the advanced tab in the window that pops up. I can set individual devices' sample rates, but without selecting a device, I don't see an Advanced tab or a "standard" format to set. I didn't end up reproducing the same issue here with latest kdenlive 22.08.2 and Win 10.0.19045.2193. I am getting a few moments of stutter at the start of playbacks but I suspect that's better investigated separately.
After redoing my audio setup I tried again with latest Kdenlive 22.08.3 and reproduced the original crackle issue. This time I was using a virtual audio device (VoiceMeeter VAIO), and noticed that the crackles only happen on the surround sound channels (i.e for 7.1, on channels other than front left or right). Changing my virtual device from 7.1 to stereo and restarting kdenlive caused the crackling to stop. Changing the sample rate did not seem to have an effect. The Realtek audio chipset may be unrelated as it should be uninvolved at the moment - nothing is plugged into it and everything is routed through Voicemeeter to a USB device.
Thank you for the feedback. That means you have only crackling when you set your audio device to more than 2 audio channels for playback. Correct?
Yes, that appears to be the case.
Hello, I have downloaded the latest version available 24.05.2, I was evaluating its functions, I have in V2 a video without audio, then in V1 a video title without audio and finally in V2 another video with its corresponding audio in A2. I have no problems, everything works spectacularly. I added in A1 a 6 second music audio, starting from 00:00:00:00. This audio was previously normalized, it has no clicks or any artifacts. When I press play all the videos look perfect, the audio of the v2 video that starts at second 00:00:04:00, sounds perfect, However the A1 audio has many cracks. I have tried all the recommendations in this report and in other sources, but everything is the same. I have discovered that if I move the A1 audio from the beginning to any other position, everything sounds perfect, if I return it to the beginning it gives problems again. Could this be the same problem reported here? Thanks for any help.
Hi Erick, First thing would be to check if these audio cracks also appear in the rendered video. If not, this might be related to your audio setup / config. If the cracks also appear on the render, would be great if you can test the current development build that contains some fixes for audio issues (I am assuming you are on Windows?): https://cdn.kde.org/ci-builds/multimedia/kdenlive/master/windows/

I don't have any insight on Erick's issue (honestly I think it's a different one) but I can still reproduce the original issue in 24.08.1.
If you have no crackling on the rendered video then it’s an audio setup issue on your PC. If it’s on your PC try the following: windws+r -> enter “mmsys.cpl” -> playback -> set your device to 44100 Hz. Is the crackling gone?
