ASIO4ALL v2 not visible in host audio configuration menu
There are two possible reasons for this: Either your audio application does not support ASIO or you
installed ASIO4ALL v2 as an underprivileged user. In the latter case, please log on as Administrator and
install ASIO4ALL v2 again. Once successfully installed, ASIO4ALL v2 should not require Administrator
privileges anymore in order to run.

Audio device flagged as “Unavailable” or “Beyond Logic” even though it is not in use elsewhere
You want to make sure the “MS GS Software Wavetable Synth” or anything by a similar name is not
enabled anywhere in you MIDI setup. The ASIO4ALL Web Site has further information on that.
If any such “Software Wavetable Synth” (sometimes in disguise as “...DLS Synth...”) can be ruled out as
the cause, try to restart the audio host application. Sometimes, when switching from another driver to
ASIO4ALL v2, the previous driver will not release the audio device in time.
If the device is an USB/PCMCIA/FireWire device, close the ASIO4ALL control panel, unplug the
device, plug it in again and re-open the ASIO4ALL control panel.

Cannot play sound from another application when ASIO4ALL is active
This by design. As close to the hardware as possible means that all the software mixing provided by
Windows will be bypassed. Without any software mixing - and the associated latency and bit mangling -
you are stuck with the hardware mixing capabilities of your audio device. Most of the time, there simply
are no hardware mixing capabilities at all.

(Vista) The meters are moving, everything looks o.k. - But there is no sound
Drivers for High Definition Audio devices have a habit of listing SPDIF outputs before the analog ones.
As a consequence, the first two or more ASIO channels will be routed to SPDIF, if you use the default
configuration. You can change this by either disabling the SPDIF output in the ASIO4ALL control panel
or correctly assigning ASIO channels in your audio application.
