2.4.4 isapnp - wrong set of resources chosen
Hi!
Robin Cull and I have OPL3-SA2 isapnp cards. Sometimes we get assigned the wrong resource set. These cards do not take kindly to Alternate resources 0:1 Priority acceptable, in fact they are completely broke, so it is important to us that they get their first choice ;-)
The trouble is that isapnp auto conf does not always take the first choice, even when it is available! This happens to me everytime I unload and reload the opl3sa2 module, but can also be seen after unloading the module by doing
card 0 YMH0020
dev 0 YMH0021
deactivate
auto
activate
The second config is chosen (see attached /proc/isapnp). However, activating the first config by hand works fine - on reloading the module it plays sounds just dandy.
card 0 YMH0020
dev 0 YMH0021
deactivate
port 0 0x220
port 1 0x530
port 2 0x388
port 3 0x330
port 4 0x370
dma 0 0
dma 1 1
irq 0 5
activate

Hmmm, interesting. I'd noticed this when testing the ISA PnP changes to the driver, but since the config the in-kernel PnP code was picking worked on the two machines I tried, I thought it was a relatively harmless glitch. I had little success parsing the PnP driver myself when I tried, and unfortunately I've little time for working in depth on sound stuff at the moment. I'm willing to test out any suggestions, though.
