Behringer FCA610 and UFX1604 is confirmed to require more time till transmitting packets after establishing connections. This seems to be a quirk of DM1500 ASIC which ArchWave produced.
For this quirk, this commit extends the time to wait up to 2 seconds for such devices. As a result, in worst cases, below userspace functions require 2 seconds to return. - snd_pcm_prepare() - snd_pcm_hw_params() - snd_pcm_recover()
