[alsa-devel] [PATCH] opti931: additional check for OPL3 device

[Krzysztof Helt]

Guys,

Look at the code. Shifting the fm_port address by 8 (Rene's) is correct way to do as the OPL3 is searched at fm_port and fm_port +2, but the OPL4 is searched at fm_port and fm_port -8
(which will be the fm_port before shifting).

Is the OPL4 located at 0x380 and 0x388 or 0x378 and 0x380? If the former, the Rene's patch is correct.

Regards,
Krzysztof
