:-)  You have better luck than I do -- but I shall not give up yet.

I just obtained the Creative Audigy 2 NX USB today, and while it
looks promising when I connected it (uaudio finds it, and recognizes
what it can do), it doesn't quite seem to be able to play back yet.
I haven't tried -- I just saw the errors below, and `mixer' reports
it's only mixer-aware.

I bought this because I think I read on the NetBSD list that one
developer had no problems with it.

This is a 16/24-bit card, capable of 96kHz sample, and 5.1 audio.
I think that its capabilities are fooling the FreeBSD code -- when
I search the NetBSD code for this, I can't find this check.

play channel supported format list invalid
pcm1: chn_init(pcm1:play:0) failed: err = 19
pcm1: pcm_chn_create(ua_chan, 1, 0xc19f4a80) failed
record channel supported format list invalid
pcm1: chn_init(pcm1:record:0) failed: err = 19
pcm1: pcm_chn_create(ua_chan, -1, 0xc19f4a80) failed

This is right after uaudio_query_formats.  I need to add debugging
to see what is being found, but from reading the uaudio_query_formats()
code in uaudio.c (the source which I have, based on the PRs and 4.x),
it may have problems with the capabilities of the card.

There is quite a bit in my dmesg that I need to look at, later.
I'll also reboot into NetBSD and verify its operation there, as
well as add hacks to try to make it work sometime soon...

Do not be ashamed, we all make mistakes like this :-)


Oh, this Audigy USB card is the one I mentioned in my last mail
that I would report if it worked or not...


thanks
