So I was having a blast (esp. in open firmware ;) ) with my new G5.
Compiled Cinelerra-gg on Slackware ~current ppc32 (gcc 15.2.0). But sadly sound was broken? I suspected ffmpeg but even native way sounded wrong, but rendered correctly?!
Turned out both ALSA and Pulseaudio hardcoded LE variant, and at least on Slackware alsa offered BE variant - picked by speaker-test utility.
I added code to use this or old variant depending on
BC_Resources::little_endian and it seems to sound fine now on both outputs?
Can you please test on le ? (usual intel/arm)
