1 - I will see what I can do to make alsa-lib optional for various configs.
2 - Building alsa-lib has no dependency on the host system's audio setup.
The problem you are seeing is indeed a problem with your build environment,
and what tools you have installed. More information is needed about our
build system and target config before I can help you.

Subject: Problems with ffmpeg and alsa-lib
I have two problems with libffmpeg and alsa-lib, both in trunk and BB:
1) Is that libffmpeg always selects alsa-lib, even when I only select
libffmpeg-mini. According to the Makefile only libffmpeg-full is
supposed to depend on alsa-lib. If i remove that dependency from
libffmpeg-full in the Makefile I can compile all variants... What's
wrong here? and is the alsa-lib dependency really needed?
2) I can not compile alsa-lib on my platforms (ar71xx and au1000 - both
don't have a sound card), it fails with the following error:
checking for mips-openwrt-linux-gcc... gcc
checking whether the C compiler works... no
configure: error: in
configure: error: C compiler cannot create executables
This does not look related to having a sound card or not :(
In the meanwhile I have solved the problems by removing the alsa-lib
dependency... Any ideas for a real fix?
