Una premessa: mi è sembrato di capire che bisogna entrare nelle impostazioni dei driver Alsa. Siccome ho faticato parecchio a settarli nel migliore dei modi, adesso, nel provare a installare il modem 56k interno, ho "terrore" di andare a toccare impostazioni della scheda audio, e di fare errori irreversibili...
Per questo motivo, se la procedura è molto complessa, forse lascio perdere (il modem 56k mi servirebbe raramente).
Detto questo, posto il conteunto di Modem/ModemData.txt almeno perché mi facciate capire quale è la procedura esatta, e mi diciate se a vostro avviso può interferire con il corretto funzionamento di Alsamixer e dell'audio in generale:

There are no blacklisted modem drivers in /etc/modprobe* files
PCI slot 00:1b.0 has a High Definition Audio Card
The Advanced Linux Sound Architecture (ALSA) packages providing audio support,
also includes drivers for some modems. The ALSA diagnostics are written during
bootup to /proc/asound/ folders.
The ALSA verion is 1.0.15rc1
The modem cards detected by "aplay -l" are:

with USB and bridge devices not displayed.
If your modem is connected by an external serial cable,
or mounted internally on an ISA card, scanModem would not access it.
Try with Root permission
$ sudo wvdialconf /etc/wvdial.conf
to detect these modem types and some USB modems.
If the detection is successful, read the wvdial.txt .
Edit the /etc/wvdial.conf with Root permission:
sudo gedit /etc/wvdial.conf
will be able to dial out with Root permission:
sudo wvdial
Many modems for which scanModem fails have Conexant chips.
From http://www.linuxant.com/drivers/modemident.php
get the ListModem tool, which will report on Conexant chipset modems
If the above tests fail, please provide any independent information available on your modem.
If an alternative boot into Microsoft windows can be done, do mouse
clicks on:
Start > Settings > Control Panel > Classical View (for Window XP) > System
> Hardware > Device Manager > Modems > Click on the + > Modem. Double click to
expand the graphic. Manufacturer information may be displayed. For example, CXT
stands for Conexant. Click the Diagnostics Tab. Record any hardware ID or vendor
and device information.
Next do the Query Modem and record the ATI specifications displayed such as:
ATI3 - Agere SoftModem Version 2.1.22
ATI5 - 2.1.22, AMR Intel MB, AC97 ID:SIL REV:0x27
Try to identify the modem setup file, with name perhaps MODEM.INF.
If may contain chipset Vendor informaton.

Predictive diagnostics for card in bus 00:1b.0:

High Definition Audio (HDA) cards MAY host a modem chip in their Subsystem,
and many are supported by the ALSA audio+modem driver snd-hda-intel
A modem was not detected on HDA card 8086:27d8.
If another modem card is present, then most likely 8086:27d8 does not host a modem.
If another modem card has not been detected, then possibilities are:
1) A Conexant modem chip is present on 8086:27d8, as Conexant chips
are frequently not detectable by ALSA diagnostics
2) The modem may be of the older non-PCI Controller Chipset (hardware) type.
Try detection with Root permission:

Softmodem codec or chipset from diagnostics:
from Archives:
Lacking a dsp (digital signal processing) chip, the modem is a software
intensive or "softmodem" type. Its primary controller manages the traffic
with the CPU. But the software needed is specified in the Subsystem.
-----------------------------------------
Support type needed or chipset:
Support can likely be achieved through two mutually exclusive alternatives:
1) The hsfmodem software for Conexant chipset modems: Read Conexant.txt
The following ALSA alternative CANNOT work with Conexant modems.
2) An ALSA modem driver plus slmodemd. Read Smartlink.txt for details, and
to test get the package SLMODEMD.gcc4.1.tar.gz from:
http://linmodems.technion.ac.il/packages/smartlink/

The base of the UDEV device file system is: /dev/.udev
Versions adequately match for the compiler installed: 4.1.3
and the compiler used in kernel assembly: 4.1.3
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.1
linuc_headers base folder /lib/modules/2.6.22-14-generic/build
However some compilations and executable functions may need additional files,
in the FileNames.h (so called kernel "h"eaders) collection installed in /usr/include/ .
For martian_modem, additional required packages are libc6-dev (and for Debian/Ubuntu, linux-libc-dev). The also required headers of package libc6 are commonly installed by default.
If a driver compilation fails, with message including some lack of some FileName.h (stdio.h for example), then
Some additional kernel-header files need installation to /usr/include. The minimal additional packages are libc6-dev
and any of its dependents, under Ubuntu linux-libc-dev
If an alternate ethernet connection is available,
$ apt-get update
$ apt-get -s install linux-kernel-devel
will install needed package
For Debian/Ubuntu related distributions, run the following command to display the needed package list:
Otherwise packages have to be found through http://packages.ubuntu.com
Once downloaded and transferred into a Linux partition,
they can be installed alltogether with:
$ sudo dpkg -i *.deb
