Hi Christopher, Thanks for reviewing the patch. > From the diff, it looks like oss is being disabled, rather than > unbundled. What's the reasoning behind disabling it? OSS is not needed since it was superseded by ALSA and it does the job. I disabled it because it's not at all used in Guix and also not needed as we have ALSA.

I tried it but autoconf or automake looks for it and gives error, before starting building.
