===== 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 modem cards detected by "aplay -l" are: None
The /proc/asound/pcm file reports:
-----------------------
00-00: ALC262 Analog : ALC262 Analog : playback 1 : capture 1
about /proc/asound/cards:
------------------------
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfae78000 irq 21
PCI slot 00:08.0 has a High Definition Audio Card
The drivers are in the kernel modules tree at:
/lib/modules/2.6.31-20-generic/kernel/sound/pci/hda/snd-hda-intel.ko
/lib/modules/2.6.31-14-generic/kernel/sound/pci/hda/snd-hda-intel.ko
The HDA diagnostics did not recognize a modem chip on the audio subsystem,
though a Conexant chip modem might not be recognized.

The AgereSystems/LSI agrsm code supports compiling of a agrmodem + agrserial driver pair.
There are a few different chipsets which use this driver pair, but they use different code resources:

* KV == latest kernel release with a reported success
!! Latest update with major credit to Nikolay Zhuravlev
But see conflict issue: http://linmodems.technion.ac.il/bigarch/archive-nineth/msg02753.html
For the 11c11040 chip with kernels 2.6.31 and later a change in a modules loading settingmay be necessary.
Within the file /etc/modprobe.d/alsa-base.conf (or equivalent for your Distro), change the phrase:
options snd-hda-intel power_save=10
to:
options snd-hda-intel power_save=0
or the agrsm drivers will not function. For Ubuntu related systems this can be done with:
$ sudo gedit /etc/modprobe.d/alsa-base.conf
Report from Bjorn Wielens:
Please note- trying to load the modules on a OpenSuSE 11.2 system gives
an error about the module_version symbol. Using:
# modprobe --force agrmodem
# modprobe --force agrserial
is necessary to load the drivers, and does not appear to cause ill effects.
All of the above packages are dkms competent. This means that if your Linux distros dkms package
is previously installed, if provides for future updates matching forthcoming kernels.

Support type needed or chipset:
Support can likely be achieved through two mutually exclusive alternatives:
1) The hsfmodem software for Conexant chipset modems: Read DOCs/Conexant.txt
The following ALSA alternative CANNOT work with Conexant modems.
2) An ALSA modem driver plus slmodemd. Read DOCs/Smartlink.txt for details, and
to test get the package SLMODEMD_gcc4.4_alsa1.0.20.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: 4.4.1
and the compiler used in kernel assembly: 4.4.1
The patch utility is needed for compiling ALSA drivers, and possibly others.
Minimal compiling resources appear complete:
make utility - /usr/bin/make
Compiler version 4.4
linuc_headers base folder /lib/modules/2.6.31-20-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.
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
Checking settings of: /etc/ppp/options
asyncmap 0
noauth
crtscts
lock
hide-password
modem
proxyarp
lcp-echo-interval 30
lcp-echo-failure 4
noipx
In case of a message like:
Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
see http://linmodems.technion.ac.il/bigarch/archive-sixth/msg04656.html
For guidance on FAX usage, get from http://linmodems.technion.ac.il/packages/ get faxing.tar.gz
It has samples for a modem using port /dev/ttySL0, which must be changed to match your modem's port.
Read Modem/DOCs/YourSystem.txt concerning other COMM channels: eth0
Which can interfere with Browser naviagation.
Don't worry about the following, it is for experts should trouble shooting be necessary.
