[Alsa-user] Build 32 bit alsa-plugins on 64 bit system

2007-09-23 Thread Robert Gruendler
Hi there,

i'm having some troubles compiling a 32 bit version of the alsa-plugins 
on my Fedora x64 system.

When compiling and installing, by default 64 bit shared objects get 
installed in /usr/lib. To compile 32 bit versions, so far i have tried 
the following:


used 'setarch i386 ./configure' to create the makefile.

Edited the makefile and added -march=i386 and -mcpu=i386 manually to the 
CFLAGS.


This however, still builds 64 bit libraries.

Does anyone have a hint how i could accomplish that ?


thanks

-robert

[Alsa-user] Laptop problem

2007-09-23 Thread Per Andersson
Hello everybody,

when I try to use sound on my laptop it works fine
on the console, but when I start X11 and use programs
like sox or aplay the system hangs badly ( i need to
remove the battery to get going again ). Same thing if
sound is playing when i start X11.

(Siemens 510 Scenic + Slackware 11.0 + alsa ) This does not happen on my
other computers (same software).

Any ideas?

Per

[Alsa-user] M-Audio MobilePre - snd-usb-audio

2007-09-23 Thread James Shatto
I have the M-Audio MobilePre to use as a preamp for weak microphones.  All of 
my current mics are currently 1/8 or adaptered to 1/4.  I've gotten the 
device working as an audio out device.  But I have not been able to capture 
from it.  I do not have any XLR3 mics and I think it's defaulting to those 
ports for input.  How do I get it to input from the other available ports?  
Output works fine so far on either the laptop or desktop.  There's some weak 
hint of a mic on the other end on the laptop, but so far no such luck on the 
desktop.  I have to normalize it to hear any hint of a recording, and it's 99% 
noise at that point.  I've played with the very few mixer settings and knobs on 
the device with little effect.  Aside from adjusting the level of the noise of 
the device itself.

I'm at a loss now.  Any documents I should be referencing?  any hints for using 
one or all of several sound devices?  For the moment I have 
/etc/modprobe.d/alsa-custom setup for the one usb device on the desktop.  I 
have it setup for two on the laptop and it works, but defaults to card0 for 
pretty much everything.  No asoundrc or dmix setups yet.  qjackctl just shows 
two capture and two playback channels for the device which appear to be 
connected correctly.  I just bought the device used from craigslist, and am 
trying to determine if it works.  Aside from the faulty USB cord that came with 
it, it appears to work.  At least for output.

Thanks,
- James

Burried deep in the manual is an indication that normal computer mics are 
powered by current from the computer.  This unit does not provide that current. 
 Therefor the only mic I have that works on it is an old radio shack optimus 
mono mic that probably cost $10 a decade plus ago.  It runs off of a AAA 
battery and only recently started working again after banging it around for 
bit(literally).  So much for my giant squid audio lab collection.  And so much 
for gaining stereo recording capabilities for 1/8 style mics from this unit.  
At least it has XLR type connectors so I can start working on my other mic 
collection.
