I don't "know", but I suspect that it started back with the 755 series, where
they wanted to include modem capability and sound capability. Use of the Mwave
DSP was a promising design choice, that should have allowed both, while
providing the capability to improve features along the way with new software
downloads.
IMHO, the 755CE implementation botched it. The modem was always tempermental
and not always compatible with ISP hardware. On the other hand, the sound
capabilities taxed the CPU and required a 1-2 second delay before actual
vibration of the speaker started. I fairly quickly disabled the Mwave modem
function and installed a Megahertz modem / Ethernet combo card. The last time
I re-installed Windows on my 755CE, I didn't even install the Mwave code.
On the 770ED, I've still got the Mwave code loaded, but disabled the modem
capability, again in favor of a Megahertz combo card. Anyone know whether /
how the Mwave code can be completely removed from the 770ED? Is it actully
used / needed for anything else other than the modem capability? Sound? Video?
Video capture? DVD playback? Anything?
Thanks!
