I have several questions about the modularized Tropez drivers (mad16, ad1848, maui) under 2.1.90.
a) Random digital-sounding noise appears in very small bursts, often like clicks, which roughly correlate with large video actions (focus change, new window, virtual screen change, etc) under XF86. Is this a known problem? FWIW It didn't happen under 2.1.58. (if not digital, could some mixer channel be accidentally left open to pick up ambient emi from other boards ? )
b) The firmware code (sound_firmware.c) appears to assume that the card operating system microcode will be less than 64K. For the Maui, the code is ~94K resulting in an "Invalid firmware" message when the module is loaded. Is it safe to increase this number(seems to work), or am I flirting with death by crossing some memory segment boundary ?
thanks, Matt Martin
