I'm 99% sure you can only switch the bitrate on the r16 from 16-bits to 24-bits. The samplerate is always set to 44.1kHz. Perhaps configuring jack to use 44.1 will solve the problem? Just a thaught, i still havn't got my thumb out to try Clemens Patch :/ Have a good awoken time y'all! *set On 2013-10-21 22:57, Natanael Olaiz wrote: > El 10/18/2013 10:04 PM, Natanael Olaiz escribió: >> El 10/18/2013 08:27 AM, Clemens Ladisch escribió: >>> Natanael Olaiz wrote: >>> >>>> [...] >>>> On the other hand, audio doesn't seem to works straightforward.
