> Removing the PCIe graphics card and installing an old NVIDIA FX5500 PCI card in the other PCI slot allowed the Maudio card to be recognised (although unusable due to the NVIDIA stealling the bandwidth). So I tried installing and old Soundblaster PCI card into the other slot with my Maudio next to it. This allows both to be recognised under aplay- l as below:

> Now, you can see above that both the Maudio and the Soundblaster are being identified as the same Device number: 0. So using this configuration fails (no way to choose between the two and it never output to the Maudio whatever I tried). So I blacklisted the snd-emu10k1 driver in /etc/modprobe.d/blacklist.conf and that did the job - now only the Maudio is shown (and onboard if I enable it in BIOS as above). Maudio is now useable.

> Now, I dont know why or how this would be happening. My only thought is that there is an issue at kernel level either with how the PCI slots are being addressed OR with the snd modules themselves. I should point out that when I tried an old PCI modem card it didnt do the job - the modem showed up in lspci -vvv but the eeprom error was still showing in dmesg and the Maudio was again not detected.
