[Openvortex-dev] delta > 1

[Alexey Gankov]

Hi!
It's a great that aureal chips now can generate sounds.
Well, I tried last drivers and get clicks, while playing any long sound.
At the Audio out it looks like 8kbyte block ok, then ~200 bytes wrong 
and so on. These ~200 bytes looks like a part of sound from wrong place 
(I generate sine signal and digitize it :)
Well, log has the following lines:
vortex: start 1
adbdma: 1, temp 1FA7C03F, per virt 0, per bytes 101
vortex: pointer = 0x3F
SDAC detected
adbdma: 1, temp 21008D, per virt 3, per bytes 101
vortex: pointer = 0x390
adbdma: 1, temp 23303F, per virt 3, per bytes 101
vortex: pointer = 0x342
adbdma: 1, temp 20A003, per virt 3, per bytes 101
vortex: pointer = 0x306
adbdma: 1, temp 2280B7, per virt 3, per bytes 101
vortex: pointer = 0x3BA
adbdma: 1, temp 20307B, per virt 3, per bytes 101
vortex: pointer = 0x37E
adbdma: 1, temp 22202D, per virt 3, per bytes 101
vortex: pointer = 0x330
adbdma: 1, temp 2400E1, per virt 3, per bytes 101
vortex: pointer = 0x3E4
adbdma: 1, temp 22B0A5, per virt 3, per bytes 101
vortex: pointer = 0x3A8
adbdma: 1, temp 202069, per virt 3, per bytes 101
vortex: pointer = 0x36C
adbdma: 1, temp 22101B, per virt 3, per bytes 101
vortex: pointer = 0x31E
adbdma: 1, temp 2430CF, per virt 3, per bytes 101
vortex: pointer = 0x3D2
adbdma: 1, temp 21A093, per virt 3, per bytes 101
vortex: pointer = 0x396
>>>vortex:  1 virt=0x3, real=0x3, delta = 3

adbdma: 1, temp 231087, per virt 5, per bytes 101
vortex: pointer = 0x58C
adbdma: 1, temp 20804B, per virt 5, per bytes 101
vortex: pointer = 0x550
adbdma: 1, temp 22A0FF, per virt 5, per bytes 101
vortex: pointer = 0x604
adbdma: 1, temp 2010C3, per virt 5, per bytes 101
vortex: pointer = 0x5C8
adbdma: 1, temp 220075, per virt 5, per bytes 101
vortex: pointer = 0x57A

Line marked with >>> looks to happen in the moment of click.
What is delta ? What steps could be done to solve the problem? (beside 
more reverse of winxx drivers :)

Thanks,
