How do I enable synth devices in alsa?

Recommended Posts

I googled this for several weeks now. All I can find is either people who can't get sound to work or wwaayy tooo ddeeepp how to compile kernal.

 

My sound works.

 

I want to enable the onboard hardware synth in my soundcard. Dell Inspirion 7500 laptop with EES Tech. Maestro soundcard. Really the 450MHz CPU needs a break.

 

Actually I thought the soundcard synth was the reason alsa was started.

 

Someone please point me in the right direction.

 

Thank you.

There are many variants of ESS Maestro.

What's the output of

#lspci

in a root console?

It's probably the ESS Maestro 2e, but it doesn't hurt to know for sure.

You can also give us an

#lsmod | grep snd

Yep I still think it should work I just don't know the magic numbers or where to put them. Need the hardware synth but don't have to have the mpu401 (no cable plus I'll try to get Fastlane 2 working)

 

Thanks

Which way do you try to connect to the synth device?

Jack may be necessary. The best way to manage jack is qjackctrl, although I do not know if such an old machine will complain for the resources needed.

Apparently, all needed modules are loaded, so it's not an OS issue.

I agree probably not an OS issue. But it still is a configuration issue for me.

 

here is output from kinfocenter:

Sound Driver:3.8.1a-980706 (ALSA v1.0.20 emulation code)
Kernel: Linux tc-laptop 2.6.31.6-desktop586-1mnb #1 SMP Tue Dec 8 15:43:31 EST 2009 i686
Config options: 0

Installed drivers: 
Type 10: ALSA emulation

Card config: 
ESS ES1978 (Maestro 2E) at 0x1400, irq 5

Audio devices:
0: ESS Maestro (DUPLEX)

Synth devices: NOT ENABLED IN CONFIG

Midi devices:
0: ESS ES1978 (Maestro 2E) MIDI

Timers:
7: system timer

Mixers:
0: SigmaTel STAC9721,23

 

Last week the Midi devices: line was the same as the Synth devices line is now.

 

I just need to know which config file needs to be edited and what magic numbers need to be there.

 

One of my sequencer apps may have prompted the midi devices fix.

but I really don't know which one.

 

Jack is running but ALSA should be the one to enable the built-in synth device.

 

It could be the driver needs to be updated as it may only partially support the card or the developer believes no one would want that?

 

:wall:
