Modem actually dialing but not connecting due "clicks"
in its signal.

Yes, sound stopped working, because hsfconfig 
failed to build new alsa modules and renamed old modules 
to something like snd-*.ReplacedByHsfmodem.
So no alsa-modules - no sound. 

On the other side with 2.6.27 kernel it compiles new alsa modules
without any problem.
With already patched alsa-modules (both in-kernel or separate package)
hsfconfig doesn't replace them. It just picks them up. 
There were no messages about unabling to unload modules.
/etc/init.d/alsasound restart after uninstalling driver and i have sound working.

About ubuntu :)
all just works in Ubuntu.
I've installed 9.04 for testing purposes.
Modem works as it should. And yes on both kernels.
with default 2.6.28 (with debs for it) and with generic 2.6.30 with generic alsa-driver-linuxant (source deb)
and hsfmodem- (not deb).

You can download "clicks".
Here is the archive with it - deposit[remove_it]files[dot]com/files/0fa28vj8a
it shows just clicks, i even did't try to establish connection (it's impossible due clicks) so i swithed from pulse to tone dialing as my provider supports only pulse dial-out.
You can play it with:
aplay -t raw -f S16_LE -r16000 <filename>

>  hi, i have a strange problem, after updating kernel (from 2.6.27 to 2.6.30) with in-kernel alsa i can't use modem driver anymore. With freshly installed gentoo-sources-2.6.30-r6 hsfconfig failed building modules with message: HDA support not compiled in the driver, so i decided switch off in-kernel alsa and to try out separate alsa-driver package (1.0.20) with patch from linuxant with improved support for Conexant chipsets and the HSF driver. All compiled ok. hsfconfig build modules. Modem works. But it can't establish connection due "clicks" in its signal. I have a record of it. The same version of driver works ok with gentoo-sources-2.6.27 (with in-kernel alsa) without any patching. I also have applied alsa-patch from linuxant to gentoo-sources-2.6.30-r6 to try it with in-kernel alsa (1.0.20). This works too but also with "clicks".
