SB Live & alsa - Can't Control Volume Levels


Latest Debian unstable
Linux 2.6.8 (k7)
Soundblaster Live (emu10k1)

This has been bugging me for the past few days. I have a nice new 5.1 PC speaker system and a friend of a friend of a friend says that I should use ALSA to get the best out of it. I was currently using OSS (I think, I just modprobed emu10k1 awhile back and it worked fine since).

So I installed ALSA, rmmod'd emu10k1, blacklisted emu10k1 and emu10k1-gp in hotplug's blacklist (after an issue I googled for), ran alsaconf, selected my card, blah blah fine, no errors, took a look at the alsa mixer and made some changes to the obscene number of sliders that there seemed to be now.

Loaded up xmms, went to the configuration, selected alsa, selected my EMU10k1 card, selected Master for the sound control, queue'd up some Magnetic Fields, played around with the mixer to get a good bass, surrond, and center and all seemed well, except I couldn't change the volume. At all. I couldn't raise or lower it no matter what I did with the xmms slider. In the mixer I couldn't get results with any of the unGodly amount of sliders there either. I tried setting xmms's default chanel/slider/whatever thing to others and it still does nothing (although now I don't see why this would make a difference if Master doesn't work).

In other applications it's the same thing, either the sound is too high and the mixer doesn't do jack. In XMMS however I can use the "software" to control the volume but I'm still not comfortable with the fact that I can't control the levels themselves, not all applications have a "software" control and some apps like xine have a "software" volume control where anything above the first little "tick" mark is incredibly loud.

Now I have to resort to posting this thread because I'm all out of ideas. Googling seems to show a lot of similiar issues regarding things like oss modules (emu10k1) still being loaded but as shown in my lsmod output, it's not there:

That sure is a load of modules for sound though, I don't quite understand why hci_usb would be using stuff for that, although I'm not sure of what that implies.

Anyway,

mainly I was told to switch to ALSA for my full multichannel sound for my 5.1 system, if there's another way to have 3d sound without using ALSA I'd sure as hell like to know, but in the mean time this is what I have.

Help is appreciated.

I have crystal clear Digital surround sound on 6 speakers(2 sub woofers) with my SB Live 5.1
I use the emu10k1 driver and emu-tools from sourceforge.net
I don't have that ALSA crap on any on my boxes.........

the only thing in /etc/modules.conf file is

Code:
alias sound emu10k1
post-install emu10k1 /usr/local/etc/emu-script
post-install emu10k1 /usr/local/etc/emu-script restore
that's it........ALSA puts too much garbage in that file...........

Interesting. I will have to examine emu-tools once I get home from work.

emu10k1 by its lonesome certainly did work, but the output sounded like a 2 channel being emulated over my speakers or something.

Hopefully emu-tools will rectify that problem.

I don't trust alsa either, or anything with this many components.

Could you possibly post a link to emu-tools? I've been to SourceForge and
http://www.emulationzone.org/projects/emutools/

Feel like a bonehead, not being able to find it...

He means http://sourceforge.net/projects/emu10k1

I hope this works, although I can't really find a description of what emu-tools actuall "does"

Thanks. I can't say that ALSA doesn't work on my system,
but alsamixer sure has a lot of stuff that isn't usable. I'm
running the current ALSA drivers than came with Slack-10
on one system, and compiled from source on the other.
I'm going to d/l this and give it a try.
