(CC'ing alsa-devel, because I had problems with building alsa-plugins)

Help me here with two things,

1. How do I fix this and test, as in should I clone the alsa-project,

or download alsa code and fix and compile ? In case I have to clone it, can you also provide me the clone instructions.

git clone git://git.alsa-project.org/alsa-plugins.git alsa-plugins cd alsa-plugins ./gitcompile --enable-pulseaudio

If the configure script complains about missing dependencies, you'll need to install them.

After you have made your changes, I believe you should be able to test them by running "make && sudo make install". I haven't tried that myself.

I tried the "./gitcompile --enable-pulseaudio" command myself, and had this problem:

Debian doesn't ship libsndfile.la, so I tried installing libsndfile from source. That didn't help at all. I eventually figured that since the alsa build system doesn't reference libsndfile at all, libpulse must somehow have a reference to /usr/lib/x86_64-linux-gnu/libsndfile.la (even though my system has never had that file installed). I rebuilt pulseaudio and installed it, and now it works (apparently because the rebuilt version references the version of libsndfile that was built from source, which includes libsndfile.la, instead of referencing the system version of libsndfile).

Does anyone know if the build system of alsa-plugins could be improved so that it doesn't use any external .la files when linking?

2. and after my modifications, my config in asoundrc should look like this ?

pcm.pulse_dev1 { type pulse source alsa_input.pci-0000_00_1b.0.analog-stereo sink alsa_output.pci-0000_00_1b.0.analog-mono }

Yes.
