Revision	Date	Author	Comments
1.18	05-Jun-2025	nat	Fix full duplex recording for the later version of the EASC. The status reported for fifo a is inverted on the later version of the EASC.
1.17	04-Jun-2025	nat	Fix independent volumes when operating in full-duplex mode.
1.16	04-Jun-2025	nat	ascaudio(4) now works full duplex! :) ASC (non enhanced) has only been tested in an emulation though.
1.15	15-May-2025	nat	Smaller recording block size. Fixes an issue with audio blocks being skipped especially when the recording samplerate did not match the hw capabilities.
1.14	14-May-2025	nat	Missing whitespace.
1.13	14-May-2025	nat	Rearrange.
1.12	14-May-2025	nat	Remove unused code.
1.11	14-May-2025	nat	Add support for 22kHz recording.
1.10	12-May-2025	nat	Add software volume scaling to recording.
1.9	12-May-2025	nat	Return initial block of silence when starting recording.
1.8	12-May-2025	nat	Set non compressed mode for recording.
1.7	12-May-2025	nat	Add code to configure the Digitally Filtered Audio Chip. This was the missing puzzle piece to audio recording on the Macintosh. It is currently experimental and use caution when testing! It should work on most machines expecpt the PowerBook 5xx and similar due to the fact they configure the dafc via the power manager.
1.6	12-May-2025	nat	Add independent audio recording volume control.
1.5	09-Apr-2025	nat	Move version identifiers to ascreg.h No functional change intended.
1.4	13-Jan-2025	riastradh	mac68k/asc: Nix trailing whitespace. No functional change intended.
1.3	12-Jan-2025	nat	Overhaul of ascaudio(4). Simpler interrrupt function. Volume control works properly on different variants of EASCs. Alternate FIFOs identified for some EASCs. Recording still does not work as yet as microphone audio needs to be routed to the sound chip. However attempting to record should no longer cause a lockup or panic.
1.2	13-Oct-2024	nat	Match against an EASC chip that reports a different version id.
1.1	13-Mar-2024	nat	Apple Sound Chip audio support for 68k Macintoshoes. This provies a sound device and support for wsbell(4). Manual page to be added in a followup commit. As posted to port-mac68k.
