20110912 vDefsound-0.10.0 [VL7.0]

[stretchedthin]

stretchedthin has built a new Vdefsound package for VectorLinux 7.0.
vDefsound seeks to be a solution for those of us with usb webcams or other usb devices that a sometimes mistakenly picked up as the default sound card at start-up.

This is a simple script with a Yad front end. It installs to run at start up and it checks /proc/asound/modules to see if a usb device has been made
the default sound card.  If this tests true then in offers a gui interface for the user to change the selected default soundcard to one that works.
If it does not detect a usb device as the default sound device it does nothing.
You can start it from the accessories menu, but that should not be necessary.

   After testing this package please stop back here and let us know how it works for you.  Really, it would be nice to know that it works for someone else and not just me.

Well,  I suppose it works as I have it loaded and as it does nothing, being, I understand, what it is supposed to not do if the usb card is not first.

My problem, perhaps related to this thread, is that I can't figure out how to have VL 7 load my usb soundcard first. 

Headacher said, back in 2007:

So, to make sure the right soundcard is default, we have to make sure the other one becomes card 1 when the module for it is loaded. This can be done by adding 1 simple line to /etc/modprobe.d/sound:

However, when I go to modprobe.d/sound it says that it is generated by alsaconf and "Do Not Edit."

Any thoughts or suggestions are appreciated.  On my system, Twinkle and Linphone play well through my usb headset. However, youtube and all the online videos play through my onboard speakers.  Seems not to matter what I to do alsamixer.  The headset is silent.

My goal is to have the headset on and the friggin onboard speakers off.

It's quite likely that some things have changed in those past 5 years  . I'm currently in the process of moving, so my USB soundcard is already hidden deep in some box. I should have some time to look at this next week, perhaps update the HOWTO if necessary.

Here's some temporary "solutions" you could try:
- On my computer, it's usually the USB device that gets to be device 0 if it's already connected during boot. Is your headset connected during boot? I must admit though, I haven't really tried that on very recent versions, I'm still using VL 6 (and earlier for my music install).
- you could try blacklisting the module for your onboard sound if you don't want to use it at all anymore.

I'll see if I can find out something later, or perhaps someone else is in the know of a solution already.

[sledgehammer]

Not sure I know how to blacklist a module.  And booting without the usb headphones plugged in doesn't work (i.e. youtube plays through onboard speakers and not usb headset).  I tried a couple of other things, which also did not work.  What might work would be if I could find an editable version of the file which designates the onboard speakers as 0 and the usb speakers as 1.  I could then just change their order.  But I can't find an editable version of that file.

What would be nice, great even, would be if stretchedthin could get vDefsound to also operate when the onboard speakers are loaded first, as happens in my machine.  Those who, like me, can't figure out how to get the usb headphones to load first (actually, alsamixer.conf doesn't even recognize the headset) could then use vDefsound to turn off the onboard speakers and turn on the usb speakers.

[The Headacher]

Not sure I know how to blacklist a module.

You'd edit the file /etc/modprobe.d/blacklist.conf and add a blacklist entry for your onboard sound.

[sledgehammer]

The Headacher,

Would you mind taking a look and telling me which module to blacklist in order to turn off my onboard speakers?

I'll be glad to! Your onboard card uses the snd_hda_intel module.

Keep in mind that blacklisting should only prevent auto loading of the modules. If there's a script somewhere explicitly loading the module it would still be loaded.

PS. I may have been a little optimistic saying I would have time for a better look at the problem/Howto this week. Everything is still rather chaotic after moving.
