[Notion-general] There is no sound

[Thomas A. <t.d...@gm...>]

Previously when my desktop runs with gnome (dgm3), I can hear sound
without a problem. However, after switching to use notion, I notice
that I no longer able to hear any sound from media. For instance, go
to youtube, there is no sound. The same when I play video with
mplayer.

I am sure the hardware should work ok because when switching to
windows 7, I can hear sound played from media e.g youtube, etc. Also,
alsamixer shows that volume is shown up including Master, Headphone,
Speaker, PCM, Front, Front Mic, Front Mic Boos, Line, and Mic.

What files do I need to modify?

Thanks.

GNOME is a desktop environment, notion is a window manager.

GNOME runs all sorts of things in the background for you that notion does
not.

In this case GNOME was most likely running some sort of sound mixer/etc.
application which was controlling the volume of your system speakers
automatically.

You will need to find a similar application (or even just the GNOME one)
and see if you can get your speakers activated correctly (my guess is that
they are either muted or have their volume levels set to zero).

Environment I am using is Debian with kernel 2.6.34.1. Notion version
is the latest one from git ( time stamp on Sat Mar 12 00:26:18 2011
+0100). The display manager is slim, version 1.3.1. Before posting
this sound problem, I'd almost removed everything about gnome library,
such as gnome-desktop-environment, gnome-session, and gdm3.

Now I try installing pulseaudio and executing command

    ps -ef | grep pulseaudio

returns process

    /usr/bin/pulseaudio --start --log-target=syslog

but I still have no sound. Checking alsamixer, it shows the Master and
PCM are at max (100<>100).

Playing video with mplayer in terminal (e.g. tty 2), sound is not
working. Also, after reinstalling gnome-session and rebooting the
system, sound is still not available.

I think my problem is that I do not know where to check e.g. logs,
etc; how to setup sound/ mixer in notion.

So generally what e.g. sound mixer is launched when you use notion?
And where (log files) to check if it is running or not?

Thanks for help.

Seems like the problem of `muted`. But I can not be 100% sure because
previously the sound is not muted.

The way I get it worked again is

First check if it works in gdm3 by reinstalling gdm3 and choose gdm3
as the default display manager.

Second, after switching back to slim, launching alsamixer to check Master, PCM.

Third, in alsamixer screen press m to make sure the bar in Master and
PCM is not shown with MM, which indicates it is muted.

Thanks again for the help.

I appreciate it.
