   Thanks for the update. It's great to even know that you are actively
looking at it.

I noticed that in my post to you yesterday that the Firmware in my card
was listed as 'Revision 1'.


Buffer Size (Latency): 1024 samples (2 periods of 4096 bytes)
Hardware pointer (frames): 0
Passthru: no
Line out: on
Firmware version: 1

Seems a bit strange, but could certainly be correct. Just pointing it
out.

I was hoping to hear whether ANY setup of the card was required by the
user to make mixer connections. I had understood (some months ago) that
maybe some 'amixer cset' commands were required to get an older
Hammerfall 9652 to actually output audio. Is this correct? If so, does
the HDSP 9652 require anything similar, as I am doing nothing like that.

Again, if there is anything I can do to help, please let me know.

Thanks,
Mark
