ASI5111/5211 Rev F+ Adapters 2012-11-14
5111/5211 adapters starting with Rev F0 and newer REQUIRE a
driver version of 4.10.15 or later. Please download the
latest version from our Windows driver page
here or the Linux
driver page here.
ASI6000 Adapters 2007-11-13
Due to a timing issue, ASI6000, 6100 and 6200 Rev E and earlier adapters can
sometimes lock up with driver versions 3.00 and later. In ASIMixer, the lock up is observed as a "1025" error.
AudioScience recommends that driver 2.97 be used instead with these early revision
ASI6000s. Driver 2.97 can be found here. These adapters are not supported in the Windows 7 drivers.
ASI4000 Adapters 2007-07-25
The ASI4100, 4200 and 4300 series
adapters were designed, tested and qualified using then current generation motherboards and chipsets. Since that time,
motherboard chipsets have changed, and due to the fact that the above cards are no longer being manufactured, we cannot
guarantee that they will work with any recent motherboards/chipsets. Specifically we have noted that motherboards based on the
Intel 9xx series chipsets can cause ASI4300 series adapters to malfunction. Malfunctions include, but are not limited to,
failure of the PC to boot and lockup of audio applications during playback and recording. Playback and record audio
formats may also be a contributing factor. AudioScience does not recommend
deploying ASI4000 series adapters in new
computers.
Addendum 1. 2009-01-07
Note that the advisory above applies to newer AMD motherboards and ASI4215s, even though ASI4300 and Intel 9xx
chipsets are the only adapter/chipset combination explicitly mentioned.
Addendum 2. 2009-01-07
Technical details of the ASI4000 issue with newer motherboard chipsets are as follows. The messaging scheme
between the host PC and the Motorola 56301 DSP used in the ASI4000 series of AudioScience adapters uses the
HSTR register of the 56301 for communication signaling. AudioScience encountered errata ED46 from Motorola that
caused a read of HCVR from the host to actually read HRXS instead. After working around errata ED46 in March of
2006, we still ran into an additional error condition where the TRDY bit of HSTR was set low, even though we had
not written to HTXR. There is no known workaround for this error condition. The upshot is that the newer
motherboards were causing errors in 56301 register reads that could not be worked around by software updates.
