The messages in syslog means that your Focusrite Saffire LE transfers isochronous packet to your system with discontinued sequence number. But subtraction of the counter (e.g. 0x20 and 0x60 in the last line) always results 0x40. The former(=0x20) is expected but the isochronous packet includes the latter(=0x60). I think it's any possible bug of ALSA IEC 61883-1/6 packet streaming engine and check it. I'll install Eoan kernel and test my devices. (but I don't have Saffire and Saffire LE...) I'd like you to wait for my test report.
