A have a opl3sax card which works under linux, but is not set up correctly by sndconfig. 1) The card shwows up as Card 1 'YMH0800:YAMAHA OPL3-SAx Audio System' PnP version 1.0 Logical device 0 'YMH0021:Unknown' <snip> Logical device 1 'YMH0022:Unknown' Compatible device PNPb02f <snip> in /proc/isapnp 2) Using sndconfig it will be detected and sndconfig then asks me to specify IRQ/IO/DMA settings (which should not be necessary since this is apnp card), but even if I specify the correct values, it will fail. From dmesg I see that it tries to use the ad1848 module which does not seem to be the right driver!? 3) Using sndconfig --noprobe and choosing the card from the list it will use the opl3sa2 module but fail since the module fails to activate the card. 4) Setting up the card by hand will work: a) Before loding the module I need to activate the card using -------------------------------- echo "card 0 YMH0800 dev 0 YMH0021 port 0 0x220 port 1 0x530 port 2 0x388 port 3 0x330 port 4 0x370 irq 0 5 dma 0 0 dma 1 1 activate dev 0 YMH0022 port 0 0x201 activate" > /proc/isapnp -------------------------------- b) In /etc/modules.conf I have -------------------------------- alias sound-slot-0 opl3sa2 options sound dmabuf=1 alias synth0 opl3 options opl3 io=0x388 options opl3sa2 ymode=2 isapnp=1 --------------------------------
Still broken in 7.3
I just debugged this problem. It is not a bug in sndconfig. According to modules.isapnpmap both ad1848 and opl3sa2 are listed for the dev ids. Since ad1848 comes first, sndconfig uses ad1848. If I remove the entry for as1848 sndconfig sets up the card just fine. Now what is the correct driver for this card? ad1848 does not work (No ISAPnP cards found, ....) but opl3sa2 does. See also #49942.
I thinkt the right way to fix this is by removing the YMH0021 entry from the the MODULE_DEVICE_TABLE in ad1848 since this is not the correct driver for this card. I tested this and it works fine here.
Created attachment 60006 [details] patch which removes YMH0021 from the MODULE_DEVICE_TABLE
