Alexandre Ratchov aac840d9f9 oss: Fix sio_setpar() when channel number is not set 
The trap value set by sio_initpar() was interpreted as a channel
number, causing sio_setpar() to fail.

Found and analysed by Roman Bogorodskiy <bogorodskiy at gmail.com>,
thanks

Michael Forney 7551d499a8 alsa: remove existing hardware config before setting a new one 
In Linux 5.11, a behavior change for USB audio devices was introduced[0]
that prevents changing parameters such as sample rate or period
size once they are initially set without a snd_pcm_hw_free in
between. This causes sndio to get forced to 48000 Hz and and a
period size of 4800, since those are the parameters set during
sio_open.

To fix this, call snd_pcm_hw_free at the start of sio_alsa_setpar_hw
to remove any previous configuration before setting a new one.

Duncan Overbruck 7a03da2848 Add libsndio.so.${MAJ} symlink and use it as SONAME on linux 
This avoids having to rebuild a lot of packages even if the
ABI did not break. cubeb used by firefox currently dlopen's
either libsndio.so.7.1 or libsndio.so, with the major link
this would also avoid having to patch this as long as the
ABI doesn't break without having to ship the libsndio.so
symlink outside of -dev/-devel packages.

Alexandre Ratchov f8795c056d Replace off-topic parts of the desciption by an architecture overview 
Remove useless (re)wording of what are audio(4) and midi(4), add a
quick description of sndiod as intermediate layer. Try to focuse on
what the sndio library and sndiod do instead of how they do it. As
suggested by schwarze, use the word "device descriptor" instead of
"device name" to avoid the common confusion with the device files.

Remove information already given in same sentence;

prefix. To avoid namespace conflicts, put program controls in a

The "master.level" control is renamed to "output.level" to match the
hardware name. This way snd/0 and rsnd/0 end-up with the same control
name.
