Yes, grep for "SAMPR" in the model specific config files in
firmware/export/config to see which models support which frequencies.
All the plugins should not have any model specific code but instead
depend on the features:
HW_SAMPR_CAPS & SAMPR_CAP_44

Did you try to use pcm_set_frequency() to change the playback
BTW I think the simulator is hardwired to 44.1kHz (feel free to correct
