- * Before touching these look how it works. It is a bit unusual I know,

- * and I won't add any new features although hardware has many cool
- * capabilities.
- * (Historical note: HAL2 driver was first written by Ulf Carlsson - ALSA
- * 0.3 running with 2.2.x kernel. Then ALSA changed completely and it
- * seemed easier to me to write OSS driver from scratch - this one. Now
- * when ALSA is official part of 2.6 kernel it's time to write ALSA driver
- * using (hopefully) final version of ALSA interface)

+          uses them is also built since they are only usable with a machine
