-<p class="Pp">The <code class="Nm">guspnp</code> driver provides support for
- audio subsystems using the Interwave (Am78C20x) family of ICs, usually the
- Gravis Ultrasound Plug and Play. Unlike the <code class="Nm">gus</code>
- driver guspnp driver does not require any local memory for the IC, but uses
- the codec for both playback and recording. The
- <code class="Nm">guspnp</code> driver can simultaneously playback and record
- 8- and 16-bit samples at frequencies from 5.51kHz to 48kHz.</p>
-<p class="Pp">The <code class="Nm">guspnp</code> driver relies on
- <code class="Nm">isapnp</code> to allocate suitable resources for it. This
- version of the driver only uses the first logical device of the five the
- Interwave IC has. The four unused logical devices are the ATAPI CD-ROM
- device, PnP Joystick device, legacy soundcard emulation device
- (SoundBlaster) and MIDI serial device. Support for at least ATAPI CD-ROM and
- Joystick is being worked on. This version of the driver will use 1 IRQ and 2
- DRQs.</p>

-<p class="Pp">Sometimes you can cause a hiss on either left or right channel, or
- both. You can usually make it disappear by playing random data, however this
- might not be a very nice thing to your audio equipment, but it is the only
- way I have found out to be effective.</p>
-<p class="Pp">Only the Codec is used in this version of the driver, therefore
- only 2 channels are supported (left and right). Also sound quality is
- probably worse at lower kHz compared to playing through the synthesizer
- which does interpolation.</p>
-<p class="Pp">If the implementation has a 'bad' oscillator, using frequencies
- 44.8kHz and 38.4kHz will result in incorrect playback frequency. The author
- has a GUS PnP Pro which displays this behavior.</p>
-<p class="Pp">Other members of the Interwave family have not been tested and
- don't have the glue needed to make them work. Should someone need to
- implement it, not many changes in the existing code are needed. Output
- voltage control in register CFIG2 [7] should be set differently for some
- other members of the family.</p>
-<p class="Pp">Other architectures than i386 haven't been tested. The bus_space
- abstraction has been used from the beginning, so it should work.</p>
