How to test audio functions?

Hi!
Today i received my usb audio device (cheap usb hub with audio functionality). I have installed madplay and smixer, but when i play a file with madplay, there is no sound in the headphones.
Here is the syslog part:

Is it possible to get it working?
Please help!

Just for the case somebody else has the same problem:

After trying and searching i found the solution:
there is a waveserver running which occupies the soundcard

here is the original thread:

Hello there...nice info but how you managed to install madplay?? Did you use ipkg in Oleg's firmware or you built it like in thread:http://wl500g.info/showthread.php?t=...hlight=madplay :confused: :confused:

I tried with ipkg but I get a dependency for esound and am stuck.....
maybe i need to study more all the info and build it as in the above link.
Thanks for any responses in advance.

Cheers!

madplay

Hi,

I use the Wl500g with a webcam and USB speakers (alarm system)

i use only madplay i've installed on my USB harddrive, and i can play any sound (after kill Waveserver)

Hi,

My soundcards seem to be recognized correctly, but all that comes out is just silence.

I already killed waveserver&waveservermain
I'm using the very latest Oleg firmware (CR8).

When i type " madplay rastaman.mp3 -o /dev/sound/dsp -v " it produces no errors, but it decodes way too fast. And, yes, there is no sound :(

I installed Smixer (but couldn't handle it) and Lmixer. With Lmixer, I set PCM Volume is set to 100.

The Souncards i use are: (I tried one after the other)

2) 13€- Soundcard from Speedlink (bought at "Saturn)
I can't post a second dmesg-output here, but there is no sound, neither.
This Soundcard has a led which should blink while playing sound (tested on my macbook) - but it doesn't

I'm not that Linux nerd - so maybe it's just a silly mistake somewhere?

ookay, I found the solution!
http://www.nslu2-linux.org/wiki/Peri...s/AudioAdapter
"ALSA has a quite good support for USB audio devices, the
only problem could be when you mix USB 1.1 audio
devices with USB 2.0 hubs.

The CONFIG_USB_EHCI_SPLIT_ISO option in the kernel
must be enabled to cope with that."

And, in fact: if I connect them directly - or using an 1.1-Hub, both soundcards work!:)
But the problem is that i need one Soundcard directly at the router, and the other one in another room (where also my USB2.0 printer is). So i would have to buy another long usb-cable and another hubs :/

But how do i turn this kernel-option on? Do I have to recompile the whole firmware? :eek:

setmixer

Hello,
I was using smixer from this forum, but some time I needed to control separate lefst and right channels and more than one soundcard (use other mixer file than /dev/sound/mixer).
Neither of this can smixer, so I wrote setmixer. It can get and set volumes separate for left and right channels and has -f option to specify mixer device.
MIPS binary and source code are in the attachement. Maybe somebody find it useful...
