On many VIA82xx boards, the 'Input Source Select' mixer control does not work.
Setting it to 'Input2' on such boards will cause recording to hang, or fail
with EIO (input/output error) via OSS emulation. This control should be left
at 'Input1' for such cards.
ALSA Kernel Parameters
~~~~~~~~~~~~~~~~~~~~~~
See Documentation/admin-guide/kernel-parameters.rst for general information on
specifying module parameters.
This document may not be entirely up to date and comprehensive. The command
"modinfo -p ${modulename}" shows a current list of all parameters of a loadable
module. Loadable modules, after being loaded into the running kernel, also
reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
parameters may be changed at runtime by the command
"echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".

does audio. snd-bt87x is a driver for the second function. It's a sound

Audigy). The mapping from FX bus to physical output is described in
SB-Live-mixer.txt (or Audigy-mixer.txt).

VIA82xx mixer
=============
On many VIA82xx boards, the ``Input Source Select`` mixer control does not work.
Setting it to ``Input2`` on such boards will cause recording to hang, or fail
with EIO (input/output error) via OSS emulation. This control should be left
at ``Input1`` for such cards.
