Where can I upload the test sample with audio channels and sample rate change?
I found the earlier fix has a problem with initial silence addition, so making the correction now(attached diff).

make fate-filter-aresample, breaks excluding the patch too.
I have a test clip which has change in sample rate as well as channels, where do I upload, for you to take a look?
./ffmpeg -psnr -y -loglevel verbose -i ../network44-Ad48.ts -vsync 1 -async 2 -f mpegts -map 0:0 -streamid 0:48 -codec:v:0 mpeg2video -map 0:1 -streamid 0:49 -codec:a:0 mp2 -b:a:0 384000 -ar:a:0 48000 -ac:a:0 2 ../network.ts

the patch breaks
also please provide a testcase/sample file with which the described bug can be reproduced

I have often repented speaking, but never of holding my tongue.
