--- Comment #5 from Aaron Digulla <digulla@xxxxxxxx> ---
Background: We're talking about "steam" here ... you know, the game client
which tries to run Ubuntu on top openSUSE ...

That means: steam comes with a folder which contains many libraries which
already exist on the host linux (openSUSE in this case) but slightly different
versions.

There is a config option to say "run steam with the host libraries" but one of
the last updates broke that, so steam doesn't start at all when I try that.

In our case, I have two versions of libasound2 which try to load the same (new)
config file. It would be great if we could configure the config file for ALSA
at runtime.

This field was introduced only for Baytrail / Cherrytrail HDMI audio, and it
should hit only that.

I'm using onboard Intel HD audio something. I could check the exact name if
that matters (not at my computer ATM), but I'm 99% sure it's not that.

My guess is that an older version of libasound2 stumbles when it tries to parse
these options even when they are not active (=no such hardware). Is that
possible? Should ALSA ignore unknown options for uninstalled hardware? Or does
it try to parse everything (fail early)?
