Hi, this is v3 of the f_uac2 timing fixup series. Changes from v2: * swap path 3 and 4, so that the ALSA buffer wrap around fix comes in first. It's not actually a bug fix for the current code, but more a preparation to allow for smaller packets. * use the p_ssize, p_chmask and p_srate for the length calculations * prepare a sequence of packet sizes to send, and alternate over them when sending the the IN packets. The actual commit log and the comments yield some more details on that. Changes from v1: * drop UAC_EP_CS_ATTR_FILL_MAX approach and rather size the packets correctly * add a patch to fix buffer wrap problems in the ALSA buffer logic, which wasn't needed before The first two patches are just cleanups. Sebastian, could you give these patches a try? They seem to work well on a BBB setup here.
