USB soundbar as default audio device
I am trying to set up a USB sound bar on someone else's laptop running ubuntu 10.10 with a gnome desktop. Since it did not work out of the box, I thought I'd first enhance my non-existent skills in this area by first practicising on my machine with debian ‘lenny’ and no DE environment. I discovered rather quickly that what goes on behind the scenes is that said sound bar is (emulates?) an additional sound card. As a result, I have to direct each program that produces some form or other of sound output to use the second audio device rather than the default builtin sound card. I am able to get ‘mplayer’ to do this but I have no idea how I could convince the flash plugin behind my web browser to do this, for instance. Is there any way I can make the sound bar the system's default and be done with it? While testing, I tried redirection when launching programs from the bash prompt -- i.e. adding ‘/dev/dsp /dev/dsp1’ -- with unsatisfactory results: below par sound quality, loud cracks, the speakers go silent for brief periods of time, etc. I do not have access to the other laptop right now, but I would assume gnome has some sort of GUI that lets you specify your default device ‘system-wide’?

Not sure if that would help at this point. thanks, but it would help though to mention what kind of chip your usb card has (or vendor + model) Not sure about the model - the vendor is actually Logitech. $ tail /var/log/messages usb 1-1.4: USB disconnect, address 13 usb 1-1.4.4: USB disconnect, address 14 usb 1-1.4: new full speed USB device using uhci_hcd and address 15 usb 1-1.4: configuration #1 chosen from 1 choice hub 1-1.4:1.0: USB hub found hub 1-1.4:1.0: 4 ports detected usb 1-1.4: New USB device found, idVendor=05e3, idProduct=0607 usb 1-1.4: New USB device strings: Mfr=0, Product=1, SerialNumber=0 usb 1-1.4: Product: USB2.0 Hub usb 1-1.4.4: new full speed USB device using uhci_hcd and address 16 usb 1-1.4.4: configuration #1 chosen from 1 choice input: HOLTEK AudioHub Speaker as /class/input/input11 input,hidraw0: USB HID v1.10 Device [HOLTEK AudioHub Speaker] on usb-:00:07.2-1.4.4 usb 1-1.4.4: New USB device found, idVendor=046d, idProduct=0a0e usb 1-1.4.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.4.4: Product: AudioHub Speaker usb 1-1.4.4: Manufacturer: HOLTEK Not much that looks like a reference to a chip, at least to my uneducated eyes. As you notice the device doubles as a USB hub. What would a chip identifier look like? I usually setup my notebook following way *) Add the user to the audio(+video) group Did that. *) create a file /etc/modprobe.d/sound with following ## ALSA portion alias char-major-116 snd alias snd-card-0 snd-hda-intel alias snd-card-1 snd-usb-audio ## module options should go here #options snd-hda-intel index=0 model=dell-m6,ref,auto #options snd-hda-intel index=0 model=ref enable_msi=1 options snd-hda-intel index=0 model=ref #options snd-hda-intel index=0 model=hp-dv5 enable_msi=1 position_fix=1 options snd-usb-audio index=1 I currently have this: $ cat /etc/modprobe.d/sound alias snd-card-0 snd-es1968 options snd-es1968 index=0 Let me check what this does before I make any changes. This way I have always the built in card configured as 0 which means first and the usb as second Ah.. nice. The options you'll find in the kernel version /Documentation *) For user specific configuration and experimenting with alsa you can use $HOME/.asoundrc excellent!
