Hello,
I just bought an 1616M PCMCIA in addition to my old 1212m v1 and want to help improve the current driver. I wrote one little patch for those cards in the past (and some bigger patches for my experiments which were never released) and now I have some time to continue.
I'm going to add missing switches into mixer, make some changes in mixer to match the real I/O setup of each particular card model and perhaps also write some graphics patchmix like app.
Unfortunatelly, I'm unable to fix the most important bugs (at least from my point of view) dua to lack of documentation and knowlenge of DSP programming. These are:
1. non working 24bit playback. It should be on device 0,2 This device exists, but cannot be openned for playback.It is the last thing needed for serious DAW.
2. Non working S/PDIF (and probably ADAT, too) on 1616(M) microdock ports. I think tese ports uses different set of registers than PCI 1010 host card. Am I right?
3. Midi I/O works well on 1212m v1, but only when 48kHz is set. At 44.1kHz signalling is corrupted (different UART timing? How to fix it?). On 1616m microdock MIDI I/O does not work at all.
I welcome any comments, advices and patches ;)
