366981 2005-06-25 06:57:00 I have a problem where If I am transferring a high/sustained amount of data across my Lan, then the audio on my computer starts going all slow, like it is being played slower than usual. :help: Agent_24 (57)
366982 2005-06-25 08:47:00 If you got read the recent published PC World magazine, there is a section whereby it says "Avoid putting the speaker lines across or paralleled to electric cables". This scenario is known as "cross talk". Try figure another way for your speaker cables to run other than your current one.

Cheers :)

No amount of external interference will cause the quoted problem (it's too late to affect it in that manner once its in the speaker leads), its more to do with the CPU being overly preoccupied with the data transfer, with insufficient resources left to apply to continuous real-time audio decoding, hence it gets continuously "lagged", giving the appearance of running slow.

366984 2005-06-25 09:19:00 you really need to give some more info like OS, specs of pc, what make/model sound and lan cards.

it could be anything from flooded pci bus to the 2 cards being on the same irq, poor drivers, or even spyware rlated.

366985 2005-06-25 10:08:00 Operating System: Windows XP Home Edition (5.1, Build 2600) Service Pack 2
Processor: AMD Athlon(tm) XP 2600+, MMX, 3DNow, ~1.9GHz
Memory: 512MB RAM
Motherboard: MSI KT4V (MS-6712)

Both NIC's are "Realtek RTL8139/810x Family Fast Ethernet", One came from DSE - the other is a no-name brand that was given to me by a friend, One is for DSL modem, the other is for the LAN.

Soundcard is a "C-Media CMI8738/C3DX PCI Audio Device", also from DSE.

366986 2005-06-25 10:23:00 check for any updated drivers first. some of the realtek ones sometimes cause werid problems. if that dosn't help check if any of the lan cards share an IRQ with the sound card. tweak'e (69)
366987 2005-06-25 11:01:00 The generic Realtek NIC (I use this for the DSL modem) is on IRQ 18 and shares that with the SmartLink 56k PCI modem.

The DSE Realtek NIC is on IRQ 19 and does not share with anything else

The Soundcard is on IRQ 17 and does not share with anything else.

I have just updated both with the latest drivers from realtek and I'll see if the problem is still there.

366988 2005-06-25 11:13:00 I've checked for new audio drivers but the latest are from 2002, and I don't really know what else to check or try... :confused: Agent_24 (57)
366989 2005-06-26 03:42:00 It won't be the LAN "transfer" that's the problem. The Ethernet TCP/IP stack works very quickly. A 4.57 or 10 MHz PC or XT handled 10 MHz Ethernet with no problems.

The CPU time needed to get the data off and onto the disks at each end is the problem. :)
