Re: 'error: period size 48 is not supported', snd-hda-intel, si3054

Firas,

There may be two issues  cogent to the situation with your:
========
Linux version 2.6.21-rc7-ana-gentoo

  Class 0403: 8086:27d8 Audio device: Intel Corporation 82801G
     Primary PCI_id  8086:27d8
   Subsystem PCI_id  1043:1123
   Softmodem codec or Vendor from diagnostics: Si3054
with ALC880 audio components

ALSAversion 1.0.14rc1
	/proc/asound/card0/codec#1
-------------------------------
Codec: Motorola Si3054
Address: 1
Vendor Id: 0x10573055
========
One is the maturity of the snd-hda-intel for the ALC880 card,
for which there are several outstanding failure reports. The 2nd is
the problem described in
http://linmodems.technion.ac.il/bigarch/archive-seventh/msg00848.html
Unfortunately the described patch doesn't solve the problem and we are
still awaiting an improved fix from the ALSA hda maintainer.

If you can compile snd-hda-intel and its depedent drivers from
ALSAversion 1.0.14 sources, your modem might work again, as this modem
Vendor Id: 0x10573055 type did work with 1.0.13 drivers.  See
http://linmodems.technion.ac.il/archive-seventh/msg00282.html for an
example on compiling and installing these drivers.

Though I have the same problem as Maxim and the same /proc/asound/pcm, my
modem is actually not the same (different /proc/asound/card0/codec#1 - I've
attached my ModemData.txt). The modem is listed as supported but also
with "patch needed", which might be my problem, but what exactly I need to
pach and where to get those patches is not mentioned.

P.S. : By the way, I'm still running Gentoo, which scanModem failed to detect
since it apparently just read from /etc/issue.
