After hours of pulling my hair out wonder why my
Linksys WMP11 PCI card won't work... There seems to be
some kind of interference problem between my SB Live!
sound card and the Linksys card. This only happens
when I play some kind of digital music source thru the
card (mp3, wav, s3m). Problems do not occur with CD
audio (digital or analog input). The interference
prevents me from loading web pages, FTPing, etc etc. It
does not, however, prevent pinging. But every 20-30
pings I get this:

64 bytes from 141.158.70.149: icmp_seq=29 ttl=244
time=54.652 msec (BAD CHECKSUM!)
wrong data byte #18 should be 0x12 but was 0x14

64 bytes from 141.158.70.149: icmp_seq=30 ttl=244

Tech specs:
P3-800 on a Tyan S1854 mobo (Apollo Pro 133 chipset)
SB Live! MP3 (has digital out)
Linksys WMP11 PCI 802.11b wireless card (Prism2 chip)
Linux kernel 2.4.19-pre7
Emu10k1 driver version 0.19a

I will slap in a different sound card and see if the
problem continues. ANY ideas on what might be causing
this or how to fix it?

Thanks in advance,
Tom Richardson

    1. Check if everything works with the SBLive! out of the system.
    2. Check for BIOS updated from Tyan (anything that mentions
      PCI bus problems)
    3. Try to plug the SBLive! or the wireless card in a
      different PCI slot.

    The SBLive! tends to be a bit agressive accessing the PCI
    bus, this was known to cause some problems with IDE and VIA
    chipsets...

    I've had a similar problem with other prism based hardware. If
    you're using KDE try the information:irq data in the control
    panel module- are both your soundcard and wireles card on
    the same irq?

    I have a PCMCIA card and PCI converter in my PC. I solved
    the problem by changing the PCI irq of the network card in
    BIOS to "legacy/EIDE". this forced the sound card to use
    another irq whilst the network card stayed on the original
    one. Problem solved in my case...
