You've gone way over my head ...
How do I find out what flags were used to compile the kernel?

I agree ... but it looks like that is an abandoned project; at
https://garage.maemo.org/plugins/scmsvn/viewcvs.php/?root=dsp-alsa it
says the last modification was 3 years ago.  The text file "version"
says 1.0.10

I found that "apt-get source libasound2" gives me a newer version:

This version seems to install correctly, but still gives me no sound.

I honestly don't know.  :-(  It looks like a bug in m4?  Here is the

I haven't been able to find alsa-utils in any maemo/diablo repositories.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  tablet-sound: Depends: alsa-base but it is not installable

I'm sorry to be so bothersome ...
I'm just a hapless n810 owner wanting to write a very simple PCM program in C.
The file pcm.c looks like the best place to start, but the more I try
to get that working the more I'm thinking that I must be going about
this wrong.  :-(

I am appreciating all the help I've been getting here.

Has anybody else succeeded with compiling this pcm.c on an n810?
