>Description:
The audio subsystem is hostile to writeonly devices in two ways:
- it requires that you create dummy functions for the read direction
(audio_hardware_attach()) check that they are present)
- it allocates the read buffer unconditionally
For the 2nd complaint, swap read and write in the above text.
