Hello,

First of all, sorry if my English grammar is bad i'm not native English speaker.

I have Arch Linux that is currently running kernel version 3.5.4 and
PCIe sound card card Creative SoundBlaster Recon3D (1102:0012), which
is based on Creative SoundCore3D chip (aka CA0132 which is also name
used in kernel). Supposedly "basic" support for this card has been
added to ALSA in kernel 3.5 and yes, it seems to detect this card and
load right modules:

**** List of PLAYBACK Hardware Devices ****
card 0: Creative [HDA Creative], device 0: CA0132 Analog [CA0132 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

But it seems to not function right. At first there no sound at
beginning  music or video plays silently... but on random moment the
random sequenced blipy noise is played which loops only when you play
some audio, it stops when i hit stop and does back when i hit play on
any application. The sequence of noise is the same on all applications
and sometimes changes. After a while i realized this noise is looping
buffer with some random data appearing, sitting there and sometimes
changing, since when i started to playing with buffer lengths the loop
of a noise gone longer when i made buffer larger. It seems that sound
data lands in wrong place.... but i don't know, that just my thinking,
i don't know how inside works of ALSA.

So the question is, it's me (eventually distribution maintainers)
doing something wrong or it's caused by premature state of support of
the card by ALSA? If first case then what should i do to fix this
problem? but if 2nd case is a problem then i'm always happy to provide
any data from that card which would be helpful to fix this, if it's
possible.

I read up this chip support (CA0132) originally been added for
motherboards like Gigabyte G1.Sniper M3 which use this chip for
integrated sound and read that people actually getting correct sound
from it, i didn't able google anyone trying to run SB Recon3D after
3.5 kernel. Also worth mention that i compiled 3.6-rc5 kernel to check
if support gone any better, but there i didn't get any sound at all
(maybe i didn't play audio long enough?), i only had pop in speakers
when i first played the audio.

So any help will be appreciated.
