SmartDVB & LAV Filters: audio syncro problem

hello everyone, I don't know if this is the right place for my question, in case send me elsewhere.
I have a problem with the LAV and SmartDVB filters: when I watch a television program slowly develops an asynchrony between audio and video.
I recently have win10, previously on win7 the problem was the same but I solved it using Microsoft's DTV video decoder. This doesn't work on win10, so I'm trying hard to understand why LAV filters work badly, but I can't. I have tried all the combinations with various splitters and decoders but the result does not change. I use the render EVR but also changing this the problem remains.
An alternative would be to install the Microsoft decoder from win7 to win10 ... but even this road seems complex / impossible.
I would add that the change of TV channel is much slower with LAV filters than with Microsoft filters.
My system is not very powerful, I have an AMD A10-5800k with integrated graphics, 8Gb ram.
Thanks in advance

Some things that you can try that can help in this case:
[1] Windows Control Panel > Sound > Speakers > Properties > Advanced > disable the two "Exclusive mode" options
[2] Windows Control Panel > Sound > Speakers > Properties > Enhancements > Disable all sound effects
[3] Disable fast startup in Windows 10 (this helps reduce driver issues): Windows Control Panel > Power Options > "Choose what the power buttons do" > uncheck "Turn on fast startup"
[4] On laptops: Windows Control Panel > Power Options > select "High performance" power plan. If this works, then increasing the value of "Minimum processor state" in the other power plans may also solve it.
[5] Use Latency Monitor (https://www.resplendence.com/latencymon) to check if you have any driver installed that cause high DPC latency. Such drivers should be replaced with a newer (or older) version.
[6] If you have overclocked your CPU, then reset to stock speed and voltage settings.
[7] Disable hardware decoding in the settings of LAV Video Decoder
[8] Update sound driver
