[kodi-rpi-19.4-5] Audio passthrough broken

[henkv]

Audio passthrough is broken on Rpi4 after upgrade to kodi-rpi-19.4-5. A downgrade to kodi-rpi-19.4-4 fixes this issue.
I see a lot of the following errors in the kodi.log, which are not present in kodi-rpi-19.4-4:
$this->bbcode_second_pass_code('', '2022-09-16 09:43:40.070 T:11 DEBUG <general>: ActiveAE::SyncStream - average error of 302.700892, start adjusting

Hmm... the primary difference between the two versions is the use of ffmpeg 4.4.2 internally vs 4.3.2 and the corresponding kynesim patch. Other minor tweaks too. The ffmpeg version change could be to blame for the broken pass through. Would you be willing to try a custom build wherein I only vary the internal ffmpeg/all other factors the same?

[henkv]

Yes, please. Can you provide such a build? The architecture is armv7h.

You can manually download the package/packages from here for testing: http://repo-ck.com/armv7h-test/
Make sure you use the package provided /boot/kodi.config.txt so we can rule out changes there as a variable.

Changes to PKGBUILD in my matrix-downgrade-ffmpeg branch for reference: https://github.com/graysky2/PKGBUILDs/c ... ade-ffmpeg

This new build does indeed fix the issue.
I double checked by downgrading the package to v 19.4-5 and the issue was back. An upgrade to this new package fixed it again.

OK thanks for testing and letting me know. Probably better for me to ship the recommended version in the official repos. I will make this change.
