menuconfig SND_FIREWIRE
bool "FireWire sound devices"
depends on FIREWIRE
default y
help
Support for IEEE-1394/FireWire/iLink sound devices.

tristate
select SND_PCM
select SND_RAWMIDI
config SND_DICE
tristate "DICE-based DACs (EXPERIMENTAL)"
select SND_HWDEP
select SND_FIREWIRE_LIB
help
Say Y here to include support for many DACs based on the DICE
chip family (DICE-II/Jr/Mini) from TC Applied Technologies.
At the moment, this driver supports playback only. If you
want to use devices that support capturing, use FFADO instead.
To compile this driver as a module, choose M here: the module
will be called snd-dice.
config SND_FIREWIRE_SPEAKERS
tristate "FireWire speakers"
select SND_FIREWIRE_LIB
help
Say Y here to include support for the Griffin FireWave Surround
and the LaCie FireWire Speakers.
To compile this driver as a module, choose M here: the module
will be called snd-firewire-speakers.
config SND_ISIGHT
tristate "Apple iSight microphone"
select SND_FIREWIRE_LIB
help
Say Y here to include support for the front and rear microphones
of the Apple iSight web camera.
To compile this driver as a module, choose M here: the module
will be called snd-isight.
config SND_SCS1X
tristate "Stanton Control System 1 MIDI"
select SND_FIREWIRE_LIB
help
Say Y here to include support for the MIDI ports of the Stanton
SCS.1d/SCS.1m DJ controllers. (SCS.1m audio is still handled
by FFADO.)
To compile this driver as a module, choose M here: the module
will be called snd-scs1x.
config SND_FIREWORKS
tristate "Echo Fireworks board module support"
select SND_FIREWIRE_LIB

Say Y here to include support for FireWire devices based
on Echo Digital Audio Fireworks board:
* Mackie Onyx 400F/1200F
* Echo AudioFire12/8(until 2009 July)
* Echo AudioFire2/4/Pre8/8(since 2009 July)
* Echo Fireworks 8/HDMI
* Gibson Robot Interface Pack/GoldTop
To compile this driver as a module, choose M here: the module
will be called snd-fireworks.

* Without streaming, the devices except for Firewire Audiophile can mix any
* input and output. For this reason, Audiophile cannot be used as standalone
* mixer.
*
* Firewire 1814 and ProjectMix I/O uses special firmware. It will be freezed
* when receiving any commands which the firmware can't understand. These
* devices utilize completely different system to control. It is some

* NOTE:

* even if streaming. To start streaming at the current sampling rate is only
* way to revocer this state. GO46 is better for stand-alone mixer.
*
* Both of them have a capability to change its sampling rate up to 192.0kHz.
* At 192.0kHz, the device reports 4 PCM-in, 1 MIDI-in, 6 PCM-out, 1 MIDI-out.
* But Yamaha's driver reduce 2 PCM-in, 1 MIDI-in, 2 PCM-out, 1 MIDI-out to use
* 'Extended Stream Format Information Command - Single Request' in 'Additional
* AVC commands' defined by BridgeCo.
* This ALSA driver don't do this because a bit tiresome. Then isochronous
* streaming with many asynchronous transactions brings sounds with noises.
* Unfortunately current 'ffado-mixer' generated many asynchronous transaction
* to observe device's state, mainly check cmp connection and signal format. I

* NOTE:
* Fireworks changes its AMDTP channels for PCM data according to its sampling

* 0: 32.0- 48.0 kHz then snd_efw_hwinfo.amdtp_XX_pcm_channels applied
* 1: 88.2- 96.0 kHz then snd_efw_hwinfo.amdtp_XX_pcm_channels_2x applied
* 2: 176.4-192.0 kHz then snd_efw_hwinfo.amdtp_XX_pcm_channels_4x applied
*
* The number of PCM channels for analog input and output are always fixed but
* the number of PCM channels for digital input and output are differed.
*
* Additionally, according to "AudioFire Owner's Manual Version 2.2", in some
* model, the number of PCM channels for digital input has more restriction
* depending on which digital interface is selected.
* - S/PDIF coaxial and optical : use input 1-2
* - ADAT optical at 32.0-48.0 kHz : use input 1-8
* - ADAT optical at 88.2-96.0 kHz : use input 1-4 (S/MUX format)

* The data in AMDTP channels for blank PCM channels are zero.
