if you're hammerfall is configured as shown above (and no, the name change makes no difference), then the SR that it uses will be determined by your external converter connected to the first ADAT port. nothing that ALSA does (or any program using ALSA does) will alter the SR. thats because you are synced to ADAT1, not the card's internal clock, thus the SR is determined by the clock signal arriving at ADAT1, which presumably comes from a converter somewhere back up the ADAT chain. its been on my to-do list for some time to make "master" the default clock mode on the hammerfall, which avoids any ambiguity about the sample rate used by the card. i've held back because its really not the right option for most studio-ish users, who have external converters that probably have rate switches on them and they expect the hammerfall to follow the switch setting. does any of this make it any clearer? its really a bit of problem that the rate setting code doesn't do a full 100% check on all this stuff. an app can set the rate to 44100, and appear to have succeeded, but it will have no difference on the actual rate if the sync source is not the clock's internal clock. this is true, btw, for most digital cards. if you tried to record at 44100, but your external converters were running at 48kHz (as you suggest they have been), then the recordings will be at 48kHz with the sync source set as shown above. --p ------------------------------------------------------- This sf.net email is sponsored by: With Great Power, Comes Great Responsibility Learn to use your power at OSDN's High Performance Computing Channel http://hpc.devchannel.org/ _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
