This commit takes ALSA firewire-motu driver to perform sequence replay for media clock recovery. Unlike the other types of device, the devices in MOTU FireWire series require two levels of sequence replay; the sequence of the number of data blocks per packet and the sequence of source packet header per data block. The former is already cached by ALSA IEC 61883-1/6 packet streaming engine and ready to be replayed. The latter is also cached by ALSA firewire-motu driver itself with a previous patch. This commit takes the driver to replay both of them from the caches. The sequence replay is tested with below models: * 828 mkII * Traveler * UltraLite * 828 mk3 FireWire * 828 mk3 Hybrid (except for high sampling transfer frequency * UltraLite mk3 FireWire * 4pre * AudioExpress Unfortunately, below models still don't generate better sound, requires more work: * 8pre * 828 mk3 Hybrid at high sampling transfer frequency As long as I know, MOTU protocol version 1 requires extra care of the format of data block, thus below models are not supported yet in this time: * 828 * 896 Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Link: https://lore.kernel.org/r/20210602013406.26442-4-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai <tiwai@suse.de> |
