- Alsa driver for Digigram miXart8 and miXart8AES/EBU soundcards
- Digigram <alsa@digigram.com>
-
-
-GENERAL
-=======
-
-The miXart8 is a multichannel audio processing and mixing soundcard
-that has 4 stereo audio inputs and 4 stereo audio outputs.
-The miXart8AES/EBU is the same with a add-on card that offers further
-4 digital stereo audio inputs and outputs.
-Furthermore the add-on card offers external clock synchronisation
-(AES/EBU, Word Clock, Time Code and Video Synchro)
-
-The mainboard has a PowerPC that offers onboard mpeg encoding and
-decoding, samplerate conversions and various effects.
-
-The driver don't work properly at all until the certain firmwares
-are loaded, i.e. no PCM nor mixer devices will appear.
-Use the mixartloader that can be found in the alsa-tools package.
-
-
-VERSION 0.1.0
-=============
-
-One miXart8 board will be represented as 4 alsa cards, each with 1
-stereo analog capture 'pcm0c' and 1 stereo analog playback 'pcm0p' device.
-With a miXart8AES/EBU there is in addition 1 stereo digital input
-'pcm1c' and 1 stereo digital output 'pcm1p' per card.
-
-Formats
--------
-U8, S16_LE, S16_BE, S24_3LE, S24_3BE, FLOAT_LE, FLOAT_BE
-Sample rates : 8000 - 48000 Hz continuously
-
-Playback
---------
-For instance the playback devices are configured to have max. 4
-substreams performing hardware mixing. This could be changed to a
-maximum of 24 substreams if wished.
-Mono files will be played on the left and right channel. Each channel
-can be muted for each stream to use 8 analog/digital outputs separately.
-
-Capture
--------
-There is one substream per capture device. For instance only stereo
-formats are supported.
-
-Mixer
------
-<Master> and <Master Capture> : analog volume control of playback and capture PCM.
-<PCM 0-3> and <PCM Capture> : digital volume control of each analog substream.
-<AES 0-3> and <AES Capture> : digital volume control of each AES/EBU substream.
-<Monitoring> : Loopback from 'pcm0c' to 'pcm0p' with digital volume
-and mute control.
-
-Rem : for best audio quality try to keep a 0 attenuation on the PCM
-and AES volume controls which is set by 219 in the range from 0 to 255
-(about 86% with alsamixer)
-
-
-NOT YET IMPLEMENTED
-===================
-
-- external clock support (AES/EBU, Word Clock, Time Code, Video Sync)
-- MPEG audio formats
-- mono record
-- on-board effects and samplerate conversions
-- linked streams

-FIRMWARE
-========
-
-[As of 2.6.11, the firmware can be loaded automatically with hotplug
- when CONFIG_FW_LOADER is set. The mixartloader is necessary only
- for older versions or when you build the driver into kernel.]
-
-For loading the firmware automatically after the module is loaded, use a
-install command. For example, add the following entry to
-/etc/modprobe.d/mixart.conf for miXart driver:
-
- install snd-mixart /sbin/modprobe --first-time -i snd-mixart && \
- /usr/bin/mixartloader
-(for 2.2/2.4 kernels, add "post-install snd-mixart /usr/bin/vxloader" to
- /etc/modules.conf, instead.)
-
-The firmware binaries are installed on /usr/share/alsa/firmware
-(or /usr/local/share/alsa/firmware, depending to the prefix option of
-configure). There will be a miXart.conf file, which define the dsp image
-files.
