====== esi maya44 pci ======

===== General =====

The [[http://www.esi-audio.com/products/maya44/|ESI Maya44]] is a PCI card with:
  * 4x4 analogue in/out. 
  * 24 bit/192kHz output, 96kHz input
  * 48V phantom power
  * SPDIF/optical output

Optional expansion card adds:
  * MIDI I/O
  * SPDIF input

Costs around 70UKP. Not seen the expansion card on sale anywhere.

===== Software =====

  * Supported in ALSA by [[http://www.alsa-project.org/main/index.php/Matrix:Module-ice1724|snd-ice1724 module]]
  * A driver is mentioned on [[http://ubuntuforums.org/showthread.php?t=868227|Ubuntu Forums]], but capabilities are not clear.
  * [[http://code.google.com/p/emutrix/|Emutrix]] Mixer for EMU cards. 0404 PCI support in V0.3 (SVN)
  * [[http://www.mjmwired.net/kernel/Documentation/sound/alsa/README.maya44|Kernel documentation]] details what should be working (see below), but has not been updated since 2008. [[http://permalink.gmane.org/gmane.linux.alsa.devel/72958|ALSA Developer list]] hints that some fixes have been applied

===== What works =====

From the README.maya44, as of February 2008:

The following functions work, as tested by Rainer Zimmermann and Piotr Makowski:
  * playback and capture at all sampling rates
  * input/output level
  * crossmixing
  * line/mic switch
  * phantom power switch
  * analogue monitor a.k.a bypass

The following functions *should* work, but are not fully tested:
  * Channel 3+4 analogue - S/PDIF input switching
  * S/PDIF output
  * all inputs/outputs on the M/IO/DIO extension card
  * internal/external clock selection

Things that do not seem to work:
  * The level meters ("multi track") in 'alsamixer' do not seem to react to signals in (if this is a bug, it would probably be in the existing ICE1724 code).
  * Ardour 2.1 seems to work only via JACK, not using ALSA directly or via OSS. This still needs to be tracked down.
