 |
|
Hi,
I got some Sound/Alsa problem under Gnome on both of my two Gentoo computers, which I wasn't able to solve with the available postings about this topic.
Both of my computers are using Alsa 0.9 which works fine before I start Gnome. Unfortunately after starting Gnome, each computer has a different problem.
Comp1:
This computer has the 'Mixer' applet in its Gnome panel, which reports an error as
soon as I log in (as root) saying: | Quote: | | I was not able to open your audio device. Please check that you have permission to open /dev/mixer and make sure that you have sound support compiled into your kernel. |
Since the snd-mixer-oss module was already loaded and I still can play sound from a xterm window using aplay or mpg123 I believe that it is a permission problem. But that is also strange because I logged in as root.
Comp 2:
The problem with this computer is that as soon as I log in into Gnome the sound seems to be blocked. When I run aplay or mpg123 from a xterm the application doesn't play anything but seems to wait for something to happen. The 'mixer' applet however doesn't report any problems like Comp1 does. |

Your problem may be due to where devfs puts devices. Some programs are difficult to change to accomodate the new system. The sound stuff is all in /dev/sound, so try making a link:
ln -s /dev/sound/mixer /dev/mixer
Or to cover all your bases:
ln -s /dev/sound/* /dev/ |

the links in /dev were already there, so that does't seem to be the cause of my problems.
Note: I believe that devfsd takes care of those links (I use the devfsd.conf settings as descibed in the Gentoo Desktop Guide). |

| I was recently getting this problem after updating a package (I think it was libpng...not sure). I solved it by re-emerging the package with gmixer - apoligies but I don't remember the name of it, however I know it was not the gnome multimedia one. |

| Thanks, re-emerging gnome-media indeed did the trick to solve my problem on Comp1. |

Sorry for more vague information, however it was a while ago and I am not at home to check...
After the libpng upgrade, there is a message which suggest you run two scripts that tell you which packages you need to update after it. The list was quite extensive on my system, around 20 packages. Again, sorry I can't give you more specific information on the name or location of the scripts...perhaps someone else remembers the details? |

Fled the crowds in Desktop Environments for the wide open spaces of the new Multimedia forum.
