Greetings everyone,
I'm writing to request assistance with getting my M-Audio Delta 44
(ICE1712) functioning under a fresh Gentoo installation. At first, I
thought I had an issue with jackd, because I could not get it to
start. I tried many configuration options, but typically got ALSA
"poll time out" messages, then jackd would die. So, I decided to
examine my ALSA installation more carefully.
Today, I decided to see if I could just get a sound to play using
aplay (from the command line without starting X11). What I notice is
that aplay just freezes at some point while processing the input wav
file. I get no sound, and I have to Ctlr-C to stop it. Here's an
example:
===========================================
$ aplay -vv /usr/share/sounds/alsa/Front_Center.wav

==================================================
You'll notice in this example that it has frozen at the 46% mark.
Other files may stop at different points. All indications (aplay,
lspci, /proc/asound, alsamixer, etc.) are that the card is being
recognized, and that the associated kernel module is loaded.
I've tried a number of sites for answers including:
http://alsa.opensrc.org/TroubleShooting
http://www.alsa-project.org/main/index.php/Matrix:Module-ice1712
http://www.gentoo.org/doc/en/alsa-guide.xml
... and countless forum posts
I have run alsa-info, and the result can be seen here:
http://www.alsa-project.org/db/?f=0703a7d0bd8da7a7b4bc387e107900acd0674a7b
I would greatly appreciate hearing from anyone with information about
further testing or configuration.
Thanks,
~Jim
