NAME
oss_usb - USB Audio/MIDI/Mixer driver
DESCRIPTION
The Open Sound System driver for USB Audio and MIDI devices.
AUDIO The Audio driver supports:
|
• |
8-96Khz Playback/Recording |
|||
|
• |
8 or 16 or 32 bits |
|||
|
• |
2, 4, 6 or 8 channel audio. |
|||
|
• |
SPDIF digital output and Input |
|||
|
• |
AC3 passthrough |
|||
|
• |
Volume control and device input mixer |
MIDI The oss_usb driver supports all MIDI devices that are compatible with the official USB MIDI specification. In addition the driver supports few devices that use their own private protocol (including some Yamaha and Midiman models).
USB MIXER
The USB Audio mixer is a new type of mixer that
doesn’t have
the normal volume controls found on AC97 or Legacy SB
devices.
The USB audio mixer provides control for selecting the
Alternate
device setting - this usually allows the device to be
switched
into a Professional audio mode (eg 24bit or 96Khz mode)
ALTERNATIVE
SETTINGS
Some USB audio devices use a feature called as alternative
settings for
bandwidth management. Typically such devices have multiple
high speed
inputs and outputs that may require more bandwidth than
provided by the USB
bus. The alternative settings feature is used to select
between multiple
low speed devices or just few high speed devices.
When the device
has multiple alternative settings an "altsetting"
selector
will be visible in the control panel for the device (use
ossmix(1) or
ossxmix(1) to change it). Alternative setting OFF means that
all
audio devices are disabled. The other settings provide
different combinations
of high/medium speed devices. You can use the ossinfo(1)
command
(ossinfo -a -v3) to find out the devices supported by the
currently selected
alternative settings and the capabilities of them.
KNOWN BUGS
Under Linux it is necessary to run the ossdetect -d and ossdevlinks commands after an USB device has been hot-plugged. Alternatively you can execute soundoff and soundon to reload OSS.
