I take that back: [22:49] xkr47: koen, seems pulseaudio has a non-floating-point resampler already [22:50] xkr47: koen, you just need to select it and it will bypass libsamplerate unless there's some non-trivial shit going on I'll try to enable that for fpuless platforms in OE regards, Koen -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iD8DBQFFsT1qMkyGM64RGpERAoc2AJ9TuUO9lIyDdfqOicxvWZaZ7naAKgCZARoR ePyUSwn5hIgOodYGnr/QdFw= =ARL6 -----END PGP SIGNATURE----- _______________________________________________ OpenMoko community mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/community
