First, I'am sorry to not read this forum, but after one month to hospital, my father is dead. Since 2 days I work again (my job, not on atari).
I had a problem with the lastest ABE, DMA transfers for MP3 play not work (tried with Aniplayer, but it's the same method for FalcAMP or the MP2 Player). Normal usage of the DMA works without problems (WAV and other audio files).
Else better results that I got was with old ABE and CTPCI_1I with Radeon memory used for the USB controller (with mouse working some time).
I hope found again energy and work again on Atari next months.
