Chocolate Doom with OPL3 Card (Linux)

[RestlessRodent]

Hello, I got an OPL3 card but it does not work with Chocolate Doom. I can however use another application that supports OPL and it plays Music just fine. So this would mean that OPL is NOT at 0x388, would there be any way to determine where it is? The card is an FM801 type.

`pmidi -l` says 17:0, which is an ALSA port number.

`lspci -vvvv`

03:06.0 Multimedia audio controller: Fortemedia, Inc Xwave QS3000A [FM801] (rev b0)
	Subsystem: Fortemedia, Inc FM801 PCI Audio
	Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx-
	Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
	Latency: 64 (1000ns min, 10000ns max)
	Interrupt: pin A routed to IRQ 18
	Region 0: I/O ports at dc00 [size=128]
	Capabilities: <access denied>
	Kernel driver in use: FM801
	Kernel modules: snd-fm801

Mind you that my IRQs are packed and I got 5 PCI cards plugged in and 1 AGP card plugged in.

If it helps:

ls -al /dev/dm*

Can you launch PrBoom from a pseudo terminal ?

The last line is just there to say that PrBoom uses Alsa.

Check the dmesg output, if you search for OPL you might be able to find what port it's on. You might also want to have a look at /proc/ioports.

Yeah that worked out well, thanks!

Took a bit to find but I made it probe around in places it shouldn't probe around in! heh.
