==CMI8788 driver status==
 
 
===2008-01-17===
 
 
New beta driver available:
 
http://www.alsa-project.org/~clemens/alsa-driver-20080117.tar.bz2
 
 
Changes:
 
*Fixed jack routing: Front and Surround were exchanged. (Hey, why did nobody notice this? :-)
 
*Internal changes.
 
 
===2008-01-16===
 
 
Changes:
 
*Yet more internal configuration hooks; no user-visible changes.
 
 
===2008-01-15===
 
 
Changes:
 
*Add more configuration hooks for card model drivers. (There should be no user-visible changes.)
 
 
===2008-01-14===
 
 
Changes:
 
*Bugfix: When sound is played to the analog front output, use the correct sample rate when copying it to the SPDIF output.
 
*Added a (read-only) control for the channel status bits of the SPDIF input.
 
*Added ALT switch for Xonar cards.
 
*Changed jack routing (exchanged "surround" and "back" jacks, except when in 7.1 mode).
 
*Made line-in exclusive.
 
*Renamed the "PCM" volume control to "Master".
 
 
To enable dmix and AC-3 passthrough, replace the files
 
[http://www.alsa-project.org/~clemens/CMI8788.conf CMI8788.conf] and
 
[http://www.alsa-project.org/~clemens/aliases.conf aliases.conf] in
 
/usr/share/alsa/cards/.
 
 
To get an updated alsamixer that supports the 8-channel master volume control, use
 
[http://www.alsa-project.org/~clemens/alsa-utils-20080114.tar.bz2 alsa-utils-20080114.tar.bz2].
 
 
===2007-11-29===
 
 
Changes:
 
*Controls for SPDIF output.
 
 
===2007-11-20===
 
 
Changes:
 
*Mixer controls for all analog inputs (but Line Input bypasses the analog mixer).
 
*SPDIF should now work.
 
 
===2007-11-15===
 
 
Changes:
 
*Playback on all other cards with AK4396 DACs should now work, too.
 
*The driver now initializes the AC'97 codec whose analog mixer is used to route the analog inputs to the ADC. Analog recording should work from all inputs.
 
*No input controls yet, all inputs (and their noise) are mixed together.
 
 
===2007-11-12===
 
 
Rewritten from scratch.
 
The driver name is now snd-oxygen (all cards except Xonar) or snd-virtuoso (Xonar).
 
 
The second most important feature, the MIDI port, now works.
 
(The most important feature, the colorful jack illumination on my Xonar card, is not controlled by software and has always worked.)<br><code>:-)</code>
 
 
----
 
 
seems to be working on all models:
 
*analog playback:
 
**at 32, 44.1, 48, 64, 88.2, 96, 176.4, 192 kHz
 
**16 or 24 bits
 
**2, 4, 6, 8 channels
 
**volume controls for all eight channels
 
**upmixing of stereo to rear and side channels
 
*analog recording
 
 
not yet implemented:
 
*front panel output

[edit] my TODO list

  1. lots of other things
  2. CMI8788 and Xonar drivers
  3. use hrtimers in the MIDI sequencer
    ca. 25%
  4. usb-audio: allow shorter-than-1ms periods for high-speed devices (just remove the code that rounds periods to USB frames)
    0%
  5. usb-audio: handle MIDI write errors better
  6. move non-public headers out of linux/include/sound/
  7. PCI: annotate in-memory data structures read by bus master chips with __le/be
  8. implement (some?) OSS 4 API ioctls
  9. test (i.e., use) alsa-python
  10. use dev_printk?
  11. various subsystem send different and too many MIDI reset commands when a port is closed
  12. usb-audio: restructure
  13. OSS emulation by redirecting to user space (like FUSE, but we need ioctls and mmap)
  14. MIDI synth: support more sysex commands
  15. MIDI synth: MIDI tuning
  16. ymfpci: MIDI synth
