Hi, Just wait till my site comes back up . I have to polish up my current version of the GUS PnP driver. The repeat loop happens if vat does not feed the GUS on time --- and I had a nice long chat with AMD about their "feature".... (The GUS PnP uses the AMD Interwave) As for the Mike sliders, I have sorted out what is going on the GUS PnP. Long time ago, I used to init my gus pnp on dos and then soft boot to FreeBSD --- with that version of the dos gus pnp driver the mic level control on freebsd used to work fine however after a dos gus pnp driver update I never managed to get the mic level working again .. Now, why am I mentioning DOS? Well, if I had had a compatible DOS sound driver it would have been a lot easier to figure out the GUS PnP Register settings on FreeBSD . >From The Desk Of Denis DeLaRoca 825-4580 : > I am running Vat 4.0b2 (compiled with the voxware audio code interface) > and the beta Gravis Ultrasound pro driver.
