alsa doesnt find my cardForum: Multimedia Topic: alsa doesnt find my card started by: darrellg1 Posted by darrellg1 on May 24 2005,18:53
Toshiba Satellite 2545 CDS, Yamaha OPL-SAx (what the x is, I don't know. Toshiba's website doesn't say). Alsa's website says it's supported, but on boot, it can't find it. If I try to manually load the module, it isn't there. Am I missing something? I installed Alsa via MyDSL.

Did you install dsl-dpkg.dsl and gnu-utils.dsl also? If not, make sure you read the info file before you download an extension. My guess is that the module is an opl3sa2 one. You can search the forum about this module. You may be able to simply do a modprobe opl3sa2 or opl3sa3 to get it working (I can't remember the exact module name). Good luck Chris Posted by darrellg1 on May 24 2005,19:24
Yeah, I followed the instrucitons that the alsa extension gave. During boot, I get the messages:modprobe: can't locate module sound-slot-0 modprobe: can't locate module sound-service-0 I tried to do a modprobe of both names you suggested, and only the sa2 did not return an error. Now I just need a sound file to test. Posted by clivesay on May 24 2005,19:52
Do a control alt backspace out of X and then startx. If the wmmix app comes up in your dockapps, you should have working sound.Chris Posted by spiff on June 08 2005,09:25
I've got an old Siemens Sceneic mobile 350 im expermenting with (yamaha opl3-Sax) and doing the modprobe opl3sa2 works like a charm, as root. I was just wondering, is there any special reason why DSL hardware detection doesn’t boot up with working sound. The hardware obviously has support since waaay back.

darrellg1,Just to clarify things - The ALSA driver for your card is "snd-opl3-sa2". The OSS driver for your card is "opl3sa2" - it's native to DSL. OSS configuration details here - < http://damnsmalllinux.org/cgi-bin....;t=3056 > You can use either driver, but obviously not both. Also, it seems that some sound cards are detected at bootup and a driver loaded, but with the wrong settings. In this case the driver should first be unloaded - "rmmod xxx" then reloaded with the correct settings. spiff, I understand that Linux has trouble detecting devices on the ISA bus, like these older sound cards. There's a Linux utility for this purpose - isapnp, but I'm not sure if Linux distributions normally run it at bootup. And in the case of ESS sound chips, the OSS and ALSA drivers actually have an option to disable isapnp, because it's known to be problematic. Having said this, there's an ALSA utility - "alsaconf" which will successfully find and configure old cards. |
