uaudio and Digigram UAX220

[Per olof Ljungmark]

Hi all,

Could someone please enlighten me of the causes of the following message:
[] ~/bin# uaudio0: Digigram UAX220, rev 1.00/1.00, addr 2
uaudio0: audio rev 1.00
pcm1: <USB Audio> on uaudio0
play channel supported format list invalid
pcm1: chn_init(pcm1:play:0) failed: err = 19
pcm1: pcm_chn_create(ua_chan, 1, 0xc2205900) failed
record channel supported format list invalid
pcm1: chn_init(pcm1:record:0) failed: err = 19
pcm1: pcm_chn_create(ua_chan, -1, 0xc2205900) failed
uhid0: Digigram UAX220, rev 1.00/1.00, addr 2, iclass 1/1

and if there is something I could do about it as a non-programmer? 
System is 5.4-STABLE, also I get the same error with a 6.0-RC1 system.

UAX220 is a professional USB audio adapter, see
