dsl@dslbox:~$ mplayer -ao alsa/http://www.archive.org./details/timkaufmanntestmp3

Hmm... I'm not sure if playing from a web address would neccessarily work and I think there needs to be a space after "alsa". Could you try this again with an mp3 file on your local hd?

One other thing to try would be to check if the mixer controls are muted, i.e.

Code Sample

# alsamixer

This should bring up a graphical representation of the mixer controls with master volume, mute, etc indicated - you can adjust the controls using the arrow keys and "m" for mute/un-mute

Hi Juanito
Sorry I didn't get back to you yesterday about this....
I've repeated all the steps so far in this post below. I don't seem to be able to uninstall oss ( or it can't find something to uninstall). I can't bring up the alsa mixer. I have installed Alsa (from the MyDSL control panel) and run it ( it detects my intel soundcard)...there's no mention of usb midi though....is that normal? It can see the usb device in lsusb but how on earth can one activate it?
Thanks again, I'm almost ready to give up but there's part of me that wants to solve this ! It could be useful for all sort of people wanting to run midi and laptops on DSL-N...maybe I'm the only one!

PS When I try to play an mp3 from hard drive see my output below....

A couple of things you could try:

1. For the commands "rmmod" and "modprobe" you may need to be the root user - you will see a # prompt rather than a $ prompt if you open an x terminal as root or you could type "sudo rmmod -f i810_audio" and also "sudo modprobe usb-audio" in the window you are using now.

2. When you install the alsa extension, there should be a menu item ("install alsa" or something like that) that appears that you have to click on to initialise the alsa /dev devices and then load the alsa modules - did you use this?

3. I seem to remember that alsamixer, aplay and aplaymidi may not be in the alsa extension - I will check, and could maybe e-mail you a modified extension I made with them included.

OK Juanito....it's difficult for me to understand why I can't just type something in to get the midi usb thing working when linux can see it on the usb devices list!

When I install Alsa....it get's to the point and says 'Ok, sound driver is configured. ASLA CONFIGURATOR will prepare the card for playing now.
Now I'll run alsasound init script, then I'll ise amixer to rasie the default volumes. You can change the volume later via a mixer.

It runs the update modules ok.....

When I try to type "sudo modprobe usb-audio" it says 'FATAL: usb_audio not found'.

You've spent a long time with me now trying to sort this out...I don't mind if you want to give up now....it must be just as frustrating for you.....
I don't mind not having audio coming out for now....so the alsa mixer I'm not worried about it working....just to try and get midi out of the laptop.......
