If you want to use the RME MADIface on Linux, it probably doesn’t work right away.
The latest version of ALSA (1.0.24) – which is probably already installed on your computer – is from January 2011. However, there was a lot of activity and bug-fixing going on since February. So you won’t have all the good stuff and a few things won’t work at all.
Especially, we couldn’t use the sound card in slave mode, and even in master mode a few sample rates just didn’t work. And, what’s really sad, the hdspmixer didn’t work.
But fear not, there is still hope!
That’s what we did:
Download the newest and freshest alsa-driver package from here: http://www.alsa-project.org/snapshot/.
Extract the package somewhere, and compile the thing:
tar xvjf /path/to/alsa-driver-220.127.116.11.gb41c8.1877.ga1e0a.tar.bz2 cd alsa-driver-18.104.22.168.gb41c8.1877.ga1e0a ./gitcompile
You may need a few development packages from your Debian (or whatever you are using) repository (maybe build-essentials, autoconf, …).
And then, as root, install everything:
And that’s it! After re-booting (or restarting the relevant services if you know what those are …) everything should work. You can set the sync-options with alsamixer and you can also use the hdspmixer.
Of course, all this will be obsolete once the new ALSA version 1.0.25 (or whatever comes after 1.0.24) will be released as Debian (or whatever you are using) package.
