Hello,
I was wondering if someone could assist me in getting my usb speakers up and running? Here is the output from lspci, lsusb, lsmod

Alsamixer shows a spot for speakers, but there is no bar above it, i.e. I can't change volume as they are not recognized?

Thank you in advance!

Isn't the USB plug on the speakers only to provide power?
I don't have this exact model, but I do have other speakers that have an audio plug and a usb plug.

Ok, I spent 2 seconds Googling, and found this hope it helps

http://wiki.eeeuser.com/howto:usbspeakers

Rerun alsaconf to detect the speakers, and right a new sound.conf.

Ipozya · 02-09-2011, 10:29 AM

Thanks for the response, disturbed1. I re-ran alsaconf with no difference. I believe, like you said, that the cord is simply for the power (blue light on speakers lights up). The computer speakers continue to be the ones playing. When I look in alsamixer, I see the line for the speakers but there is no bar above it for me to adjust. Also, I didn't see any mention of the sound.conf in the article, which only discussed the xbindkeys and kde settings (running fluxbox and have those keys adjusted already)

I do not believe that this is causing the error, but I have goth snd-pcsp pcspkr blacklisted in modules (! in /etc/rc.conf) as was suggested in arch wiki to remove beeping sound on computer.

USB speakers are really another "audio device" and need to be configured as such.

Here's an old post of mine that may help you get them working. You can probably do clicky-clicky GUI stuff now, but that post may help you get started.

Either way, please let us know how you get on.

Thanks for the link. Switching the 0-->1 in my alsa configuration file worked to get usb speakers to function. i will introduce a script in rc.local to make it so that it automatically uses them whenver they are plugged in. After having plugged in, however, my volume buttons on laptop keyboard no longer work to adjust speaker volume (neither do the ones located on speakers); I have to resort to using alsamixer. When I unplugged the speakers, it reverted back to the internal sound, but now the volume buttons don't work for these either (I am assuming it would reset if I rebooted computer). How could I fix this? Here is my xbindkeys configuration

.xbindkeysrc

Code:

# Increase volume
"amixer set Master playback 1+"
    m:0x0 + c:123
    XF86AudioRaiseVolume

# Decrease volume
"amixer set Master playback 1-"
    m:0x0 + c:122
    XF86AudioLowerVolume

# Toggle mute
"amixer set Master toggle"
    m:0x0 + c:156
    XF86Launch1

It may be that the volume commands need to include PCM, but I would like them to work universally (and it's strange that they stop working when I unplug usb still).

bump. any ideas from someone who uses usb speakers?
