Thanks for your report.

The dmesg means that your AudioFire2 transmits packets with disorder. (I
note that Fireworks driver start duplex streams for timestamp
synchronization even if you use playback only.)

I know that some Fireworks devices with a certain firmware (not exactly
identified) sometimes perform the same behaviour. Could I ask you to
confirm to see these logs always when you playback, or sometimes?
