---------------

the default driver is now the ALSA driver. see README.OSS for

information on using the OSS driver instead.

---------------

Support for ALSA 0.9 is functional and could do with widespread testing.

To build with alsa support, simply configure with:

./configure --enable-alsa

Note that this will build a binary which will work with ALSA only, and

not attempt to use OSS. In future this will be replaced with plugins

for different pcm i/o methods, which should ease binary distribution.

---------------

ALSA native support it currently not working; to even attempt to build the

code, you must configure with:

./configure --enable-experimental --enable-alsa

However, Sweep works fine with ALSA under OSS emulation.

---------------

Support for ALSA (Advanced Linux Sound Architecture) version 0.6.0 was

added by Paul Barton-Davis <[email protected]>.

To build sweep with support for ALSA 0.6.0, do:

./configure --enable-alsa

make

Paul writes:

To use ALSA, you need --enable-alsa as an arg to configure,

because just discovering ALSA is not deemed to be sufficient to use

it (at this time).

A couple of things to note:

* this is ALSA 0.6.0, which is only available via CVS right now

* this code is totally different than the code needed for 0.5.X

* you also need a ~/.asoundrc file to define the

characteristics of various "named PCM devices"

* you can define the environment variable SWEEP_ALSA_PCM to

the name of the PCM device you want sweep to use

* if its not defined, sweep will try to open a named PCM

device called "sweep"
