| I can't hear you... Being someone that wants my computer to make interesting beeps at me I wanted the sound to work on the Libretto. I haven't had much luck using the "standard" sound drivers in linux but I did find a "commercial" version of the drivers from 4Front Technologies. Folks at 4Front actually did much of the work on the orginal sound drivers and in fact there is a "freeware" version of the software with less support for different cards. Unfortunatly the freeware doesn't support the Libretto, or at least I couldn't get it to work. I didn't work too hard and just gave the folks at 4front $20 bucks and got my sound working. I ended up installing the "Generic Yamaha OPL3-SAx (YMF715/YMF719) non-PnP" driver that came with OSS. I did have to modify the "devices.cfg" in the oss directory to match the IRQ and DMA settings for the Libretto. The following is my "devices.cfg" file... /SECUREAUDIO OFF /IRQEXCLUDE 3 4 /DMAEXCLUDE 2 -opl3sax #Generic Yamaha OPL3-SAx (YMF715/YMF719) non-PnP OPL3SAX ON P530 I5 D0 d1 OPL3SAMPU ON P330 I9 OPL3 ON P388 On FreeBSD I found that the line above that describes the DMA channels would not work as shown. It would lock the computer in a horrible death. Everything was groove once I changed the line to swap the main and secondary DMA channels to: OPL3SAX ON P530 I5 D1 d0 One other note about the sound hardware on the Libretto. Everywhere else in the world has standardized on a 3.5mm (1/8") stereo jack for smaller than 1/4" headphone connections. For some unknown reason Toshiba figured it needed to shave 1/32 of an inch more off so they installed 2.5mm (3/32") jacks in this machine. Don't bother trying to find stereo 2.5mm to 3.5mm or 1/4" adapters at Radio Shack. You need to build them. You can find the parts at Mouser. Pick up a nice metal shielded plug and a jack and wire up your own adapter. Cited article |
