When I tried last time Skype on 2.x it was working just fine without any problems with ALSA and I got video cam working fine as well.

Hi BMarkus,
Thanks. Indeed, from previously reported experience looked to me like it works with Alsa but not OSS.  Looks like Alsa is the only 'reliable' way out...
Also I noticed most of light Linux distros use Alsa rather than OSS.
I do not know what is their strengths and weaknesses, but it appears to me although Alsa is widely accepted and works with key applications such as Skype. What would be a compelling reason to use OSS then?
I am certainly for the lighter and better solution but I have not seen any experience of Skype working with OSS easily...

@TinyPoodle:
By 'Sound mess' I was not referring to TCL but in general to Linux distros, that users have to sort out each time, testing whether their applications work with one or the other sound drivers...
Sound (IMHO) has been historically neglected in Linux, way behind the curve what is expected in base configurations nowadays. This is probably because of lack of focus on standardizing on key functionality and rather dissipating the effort of thousands of developers to produce hundreds of me-too distros, and mostly loaded with bloat of less than professional software.
You may not remember early days of Linux. when focus was on important features of Linux, rather than perpetuating bloat, but I remember in early 1990's, when I was able to put in the first LiveCD Linux in my CD Rom drive and it booted, and played sound! Sound was built in!
This first Linux LiveCD distro was called Yiggdrassil...

That is also related to concept/goal of a specific distro.

TC on the one hand side not including any non-essential subsystems like sound (toolkit!) and on the other hand side offering more than one choice of sound systems (build it your way!) could not be preconfigured for easy sound.
(I had actually tried OSS first - with criterium of being smaller - and was not happy with it at all, so i tried alsa and stuck with it)

If e.g. you would try geexbox which is a ~19MB distro focused on multimedia, there is a very high chance that sound and video will work right out of the box.  ;)
Similar could possibly be achieved with a TC remaster which would end up in approxymately same size.

@TinyPoodle,
To emphasize again, my complaint about sound support has nothing to do with TCL but with Linux in general. The goal is to make this function work in TCL, so installing key applications such as Skype is possible.
It has nothing to do with any 'Multimedia Distro' choice out there but rather with selecting the most effective configuration of TCL so it works and is easy to configure by user.
It is not a matter of selecting 'Another Linux Distro' to satisfy each specific need (perpetuating terribly fragmented Linux landscape) but rather to have one multi-purpose modular Linux that can do all that.
I went through many Linux distros over time and I can tell TCL is the best Linux out there for several reasons, some most important being:

1. Modular architecture of read-only components, which can be easily added.
2. Fantastic network support. None other Linux I tested comes close to TCL in network support if you forget those bloated ones I would not touch anymore...
3. Vision of TCL owner and TCL developers. Technology implemented the right way, withought redundant baggage. E.g. SliTaz (another great distro) is using HAL for Xorg, as well as other distros. However it was discovered by TCL developers HAL is not needed anymore and Xorg works just fine without it.
4. Fast development cycle.

TCL is the way and will grow in recognition. Just needs some 'showcase ISO's' or 'flavors' in SliTaz speak.

Appears to me like my point has been misunderstood, so trying to elaborate:

Working hypothesis: Create a TC remaster of 19MB - size similar to geexbox.

Pros:
  • very high chance that sound and video will work right out of the box.  (comparable to geexbox, as opposed to TC base)
  • keeping all the multi purpose extendability of TC base (as opposed to geexbox)
Cons:
  • No free choice of combination of audio/video player and sound system (as opposed to TC base)
  • up to 9 MB of wasted space for users never in need of audio or video or content with a slimmer modular solution (as opposed to TC base)

the way for TCL to become a primary communications LiveCD, that works an any machine...
I have netbooted TC many times on a 10 year old thinkpad lacking a hdd just to quickly have a VoIP phone handy.
Needed software:
  • wireless_tools.tcz
  • wireless driver as appropriate
  • firmware-*.tcz (for NIC support)
  • alsa.tcz [+deps]
  • openssl-0.9.8.tcz (required by softphone)

as a softphone i use pjsua which is a self contained binary which I had compiled on a different system, but works nicely (upxed and squashed 472KB). only deps are openssl and libasound, latter already pulled when loading alsa.

Total size of installed software < 7MB  ;D
tinycore could as well be replaced by microcore as X is not required

Hi TinyPoodle,

This is quite interesting... Would you be willing to make an extension of pjsua? This would be appreciated.  If not possible, where can I find it? Binary that is...
Is pjsua a SIP client?
Thanks much.

P.S. Out of curiousity: Which Thinkpad model did you use (the 10 years old that is), was it 600 or 770?

I would certainly be open to attempt to make my first public extension if there is a demand.
However:
  • it is not compiled under TC and i don't have any plans for a dev environment under TC with limitations of my hardware currently available
  • it is compiled on a system with openssl.0.9.7 and therefore requires a dirty (cosmetically) hack of symlinking libssl.so.0.9.8 and libcrypto.so.0.9.8 to *.0.9.7, which has always appeared to work perfectly well though
  • it is version 1.0.3, latest of the 1.0.x branch; I failed at compiling the trunk version (see details about difference here: http://www.pjsip.org/download.htm)

I haven't studied the fineprint of preconditions for submission of extensions, but i suspect with points mentioned it might not qualify.
Also i wouldn't want to interfere with WIP, particularly not by providing a binary while knowing that I would not be in a position to update it in the future as a maintainer.
In case WIP is happening on trunk branch - bmarkus can you tell? - i guess the versions of two different branch could potentially coexist though, as happens with other apps.

As for uploading somewhere, I would happily do so and post a link, but not sure if appropriate in forum.

And hey, I said the thinkpad is 10 years old - not older -, it's a A20m (PIII@700Mhz)

BMarkus,
Thanks. By saying it is work in progress to make an extension, I understand it is not mature enough to make an extension. Or you mean making extension of this is already a work in progress...

TinyPoodle,
Thanks for the info. I see that the entire process you implemented is not exactly easy for me to replicate. It would be fantastic to have a SIP client extension but I understand it requires non-trivial amount of work.

It means that I'm working on to make an extension. PJSUA is a sample application built on the pjproject VoIP framework. It requires a bit more work than usual applications to find which components are needed as it comes mixed with many other stuff which are not needed, Python tests, etc. PJSUA starts, but not tested yet with my home VoIP server (Asterisk).

So it will come in the next days if everything works well.

IIRC, I ended up with a plethora of built executables.
The only file i still have as of today is pjsua-i686-pc-linux-gnu, which appears to work fine with one single exception noted: recording calls to mp3 does not work at all (while it does to wav), so I could imagine other files of build might be required in order to record to mp3.

Good to hear, bmarkus  :)
curious... already decided from which branch?

Important!
download the OSS version of skype 2.0.72 from ARCH linux distribution, NOT from ubuntu or skype site.
for microphone to work, you select /dev/sp2 as Sound_in from skype internal menu.
