Greetings,
I had finished working on recording stuff of Maestro-{1,2,2E}.
Although the code has been working for a month or two without major issues
here, it absolutely needs more testing to ensure there's no regression.
The new code adds the following features to the stock driver:
* PCM recording in 16bit mono/stereo format.
* Adjusts the size of device buffer around 20 millisecs to reduce latency.
* Reduces power consumption while the device is idle.
* MPSAFE isr & locking (5.x only, not tested on an SMP machine)
* Works with less contiguous memory wrt new DMA buffer allocation strategy.
It doesn't address the following things/problems yet:
* It doesn't work with PT101 codec (found on some Maestro1-based cards.)
* MPU401 (MIDI) & OPL3 (FM synth) emulation
The attached file is a tarball containing the new driver source code
(without a directory name), compressed with bzip2.
To use it, simply go to /sys/dev/sound/pci, untar the archive to replace
the source and rebuild either your kernel or the module snd_maestro.ko,
depending on your configuration, will (hopefully) work.
I would be very appreciated that many of Maestro users are so kind to give
the new code a test.
Sincerely yours,
Taku

Post Scriptum to everyone:
This time I sent a tarball rather than a patch.
It is simply because the patch bloated larger than the tarball. (oh my...)
Sorry for inconvinience, especially folks who don't have any Maestro chip.
Post Scriptum to epilogue:
IIRC I had sent a mail to you with the source recently.
Had the mail got lost?
