I'm using ALSA's snd-card-opl3sa2 driver on my sid box (Panasonic 
CF-C33EJ8C, kernel 2.4.16, libc6 2.2.4-7, alsa-source 0.9+0beta9-1).
It works fine. (e.g. playing music with xmms)

Tips:

  * BIOS setting

    Sound Blaster I/O: 220h
    WSS CODEC I/O: 530h
    IRQ: IRQ 5
    DMA-A: DMA 0  (DMA 7 by default.  But it doesn't work with ALSA)
    DMA-B(Sound Blaster): DMA 1

  * ALSA setting

    - Use `alsaconf' command for creating `/etc/alsa/modutils/1.0'.

    - Edit `options snd-card-opl3sa2' line in `/etc/alsa/modutils/1.0'.
      (Removing `snd_dma1_size' and `snd_dma2_size', and adding
      `snd_isapnp')

---- 
options snd-card-opl3sa2 snd_index=0 snd_id=CARD_0 snd_port=0x370 snd_sb_port=0x220 snd_wss_port=0x530 snd_midi_port=0x330 snd_fm_port=0x388 snd_irq=5 snd_dma1=0 snd_dma2=1 snd_isapnp=0
---- 

    - `ln -s /etc/alsa/modutils/1.0 /etc/modutils/alsa' if it
      doesn't exist.

    - Use `update-modules' command for updating `/etc/modules.conf'.

  * Mixer setting

    - Remove (or rename) `/etc/asound.conf' if it exists.

    - Use `alsamixer' command.
