No, those lines are normal and are caused by builtin audio. Lot of these are in the log when you have touchscreen and system sounds enabled.

As for the problem above, most probably it just needs inserting usb audio kernel driver module which is not present by default.

Re: USB Audio
 

One may try to get extra modules from http://fanoush.wz.cz/maemo/modules-2...-custom.tar.gz and insmod everything in sound/core and sound/usb (in correct order, if you see error just try another first) and only then insert usb audio device.

Ive fallen so in love with the canola interface... but the crappy N800 sound isnt worth dropping my D2 :/
You people who have USB DACs, i take it you have a bit more experience than most people i argue with on irc who claim the n800 sound good, so my question is - how does the n800 sound with an amp from the headphone socket? does it help any at all?

Re: USB Audio
 

@ fanoush,

Im trying to get this working and I really appreicaite you throwing the kernal out there. Only problem is I have never used the insmod command before. I dl'ed your link to the documents folder on my n810. What would be the proper sytax from the terminal to do what you are saying?

Appreciate the help!

Re: USB Audio
 

Google for "man insmod".

Basically you call "insmod /path/to/a/module.ko"

Then look in the output of "dmesg" to see if there were errors; if so, you load a different module first. Take a look at the list & order of the modules loaded on this page: http://www.nslu2-linux.org/wiki/HowTo/SlugAsAudioPlayer

Re: USB Audio
 

I have later tried it with usb to audio dongle that comes with Logitech headset and it was detected and new card appeared in /proc/asound/cards but that was all. One also needs to tell the system to actually use that card instead of the builtin one which means it needs messing with ALSA configuration files and/or installing additional ALSA userspace utilities. So if you can't figure out the insmod stuff, don't bother, it needs additional tweaking.

Re: USB Audio
 

Would I just be able to use the alsa's xmms plugin device selection to point to the right device for at least xmms?

Re: USB Audio
 

It is certainly worth of checking. In that case the newbie guide to modules is :
- download modules to Documents folder
- open xterm
-extract modules:
- try to insert them (as root user) in correct order:
If it prints unknown symbol error try another one. You can see the missing symbol in kernel log via dmesg command and the symbol name can give a hint which module is missing but picking other one randomly works too :-) Try core/page-alloc, timer,hwdep,rawmidi,pcm, usb/usb-lib,usb-audio

then enable host mode, attach usb card and see kernel log for card detection. Also 'cat /proc/asound/cards' should have another one in the list.

Maybe then xmms alsa plugin configuration might work?

BTW, the link to audio on Slug that lardman posted links also el-cheapo usb sound card
http://www.dealextreme.com/details.dx/sku.5831
While I have quite good experience with dealextreme overall (14 orders so far, mostly more than 1 item, everything arrived, price/quality ratio is quite good, they send replacements for free) I was unlucky with this one. Got first one with attached but unsoldered usb connector and after soldering it didn't work anyway. They happily sent another one for free. That one worked but the audio was very distorted in headphones. They did not sent third one :-) But this was the only crappy thing I got, other stuff was better. You may have better luck with this item than me, it has good user rating so others had better luck.

Re: USB Audio
 

The order you suggested for insmod worked out great for me. Hopefully when i get home today I can try to plug in the USB sound card and see what happens. Who knows maybe it wille ven work!

Thanks tons!
