 This is a crosspost of the following bug report: https://github.com/llvm
 /llvm-project/issues/107364

 In short it seems that compiling ffmeg with -fveclib=mvec on Linux break
 the aac and vorbis decoder:
 ffmpeg -i x.ogg x.wav -> x.wav sounds bad
 ffmpeg -i x.m4a x.wav -> x.wav sounds bad

 I imagine that the test suite should catch it.

 Maybe you could help llvm devs to isolate a reproducible test case?

 I've tested with ffmpeg 7.0.2
