This is the GUI mixer gamix for the Laptop. The wide-narrow control and the treble and bass are not present on the desktop machine.
As I have had experience with both varieties, I will describe the procedure for setting up ALSA to drive them. The description here relates to ALSA 0.4.1x. I don't believe anything here is distribution specific, but the desktop machine has SuSE 6.1 while the laptop has SuSE 6.2.
| WARNING -- This material applies to version 0.4.x of ALSA, I'll update it for the Laptop when I get around to upgrading it. I no longer have the OPL3-SA2 in a desktop. |
You need to download the drivers, libraries and utils packages from the ALSA ftp site. The unpack the tar files and build and install in the order: drivers, libraries, utils.
./configure --with-cards=card-opl3sa2 --with-oss --with-sequencerI only used the sequencer option on the desktop machine (not sure if it actually works or not). I wasn't able to persuade the built-in isapnp support to work on my machine so I decided to stick with isapnptools.
Then run (assuming you're not already running as root):
make su -c 'make install' su -c './snddevices'
./configure make su -c 'make install'
This provides several mixers: amixer, gamix, alsamixer and xmixer2; a command line player aplay and an advanced control tool alsactl (I've never used it so I don't really know what it does).

It is not advisable to unmute the microphone on a Tecra 780 as the built-in microphone is very close to the built-in speaker and so if you half-close the lcd panel with an unmuted microphone, you'll get a horrible feedback loop [has the designer been fired yet? -- or merely made to listen to the results].
