===== Advanced Linux Sound Architecture (ALSA) diagnostics =====
The ALSA packages provide audio support and also drivers for some modems.
ALSA diagnostics are written during bootup to /proc/asound/ folders.

The ALSA verion is 1.0.16
The modem cards detected by "aplay -l"  are:
card 0: Intel [HDA Intel], device 6: Si3054 Modem [Si3054 Modem]

The /proc/asound/pcm file reports:
-----------------------

The audio card hosts a softmodem chip:  0x10573055

The softmodem chip 0x10573055 is in principle supported by the COMM support of slmodemd and the joint snd-hda-intel audio+modem driver, begun with ALSA version 1.0.13. For HDA cards with ALC883 chips, an upgrade to ALSA verions 1.0.15 way be necessary. Instructions for Upgrading snd-hda-intel and its dependent driver set are at:

provide audio + modem support with the modem chip residing on the subsystem.
Any particular card can host any one of several soft modem chips.

Writing DOCs/Intel.txt

Vendor 11c1 is Lucent Technologies with modem technology now under LSI Inc. Their Linux code developer/maintainer is Soumyendu Sarkar. Support for a chipset and its continued maintenance is only initiated at the request of a major chipset buyer, or comparable sponsor. Several different modem chipset types are produced:
with varying support under Linux.

Completed candidate modem analyses.

The base of the UDEV device file system is: /dev/.udev

Versions adequately match for the compiler installed: 4.2.3
            and the compiler used in kernel assembly: 4.2.4



Minimal compiling resources appear complete:
  make utility - /usr/bin/make
  Compiler version 4.2
  linuc_headers base folder /lib/modules/2.6.24-21-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 needed. The also required headers of package libc6 are commonly installed by default. Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev packages, for kernels 2.6.24 and later versions. In not included on your install CD, search for them at http://packages.ubuntu.com
or comparable Repository for other Linux distros.
When compiling ALSA drivers, the utility "patch" will also be needed.


Compressed files at: /usr/src/sl-modem.tar.bz2


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 packages.
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

To enable dialout without Root permission do:
   $ su - root  (not for Ubuntu)
       sudo chmod a+x /usr/sbin/pppd
or under Ubuntu related Linuxes
   sudo chmod a+x /usr/sbin/pppd
