Hi Peter! Do you happen to remember why the audio buffers in run_mix_test() in src/tests/cpu-mix-test.c are forced to have 8-byte alignment? I plan to replace the stack-allocated buffers with regular memblocks, and the memblock backing memory is only aligned to 4 bytes on 32-bit machines. It's possible to still have the old alignment behaviour, but that requires extra code, and if 4-byte alignment is equally fine, then I'd prefer to avoid the extra code. -- Tanu https://www.patreon.com/tanuk
