Thinkvision USB Soundbar: no sound

#1 Post by mave »

Hi,

trying a Lenovo Thinkvision USB Soundbar (F/N:40Y7616) but getting no sound.

Vendor: 0x0e6a Product: 0x0310 but Hardinfo gives "Unknown USB 2,00 device (class 0)"

I fount in the Web calling

Code: Select all

cat /bin/bash > /dev/dspX
and in Lucid 52x a bad sound is coming ;-) but alsaconf doesn't found this usb-audio card.

(No trouble on Windows XP :x )

Has anybody an idea?

Try this:
[quote]Sound muted on boot. Right-click the speaker icon in the system tray and choose Full Window. Enable Master, PCM, Front and any others that seem likely and also turn up the volume in each. This should fix things a good percentage of the time. If not, then please try Menu -> Setup -> Alsa Sound Wizard.

If no sound, open Menu -> Multimedia Tools -> Alsamixer (alsamixer, not alsawizard). Press F6 and that will show you what sound devices have been detected and configured. If yours is not the top one then arrow down and click it, then make sure everything plausible is turned up. I have to do this with my “second
The things they do not tell you, are usually the clue to solving the problem.

Thanks bigpup,

but the usb sound device is not recognized als sound card. That means:

no sound icon,

alsamixer => "cannot open mixer: No such device"

alsawizard => no supported card found...

..but surprised about this:

Code: Select all

sh-4.1# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: Device [USB Audio Device], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
Maybe to force a modprobe command...

...ah! I found inside /etc/modeprobe.de/alsa-base.conf this:

Code: Select all

options snd-usb-audio index=-1
Don't know why 'index=-2' after changing to

Code: Select all

options snd-usb-audio index=0
Puppy was able to find the ThinkVision Soundbar device and give the sound.

For now, only one mixer element (PCM-Playback-Volume) ist availabe and hardware front buttons for volume +/- have no function. Not bad :wink: Maybe this will be solved too...
