Guys,

I have 11.3 running - 64bit - lxde

i have alsa installed, pulseaudio installed.

As root - via a terminal ( using mpg123) i can play an mp3 song.


mpg123 -vv testsong.mp3 
Trying output module alsa.
Using default module dir: /usr/lib64/mpg123

testsong.mp3

Playing MPEG stream 1 of 1: testsong.mp3 ...

Above , we can see that ‘alsa’ was chosen.

As a normal user - via a terminal ( using mpg123), I CANT play this file, output shown below…

As you can see, mpg123 fails to choose ‘alsa’ ?

Is this some permission problem? it works as root but not as a normal user?

Additional Info - In firefox -> youtube -> video -> i get no sound either. i thought it was just a 64bit flash problem - so i did not bother then. Now i am stuck.

More info;

yast (as root) -> sound -> pulseadio enabled, volumes unmuted, & play test sound WORKS.

#3

i just installed mplayer2 - to gether more test data.

i find that;

-as root, ‘mplayer2 testsong.mp3’ works well.

-however as a plain user, i get an error…

oh hell, just found out that in opensuse, i have to add the said user to the ‘audio’ group.
After i did that thru yast, i can play the said mp3 song both as root and as an ordinary user.

i must say that this episode did expose my confusion over alsa / pulseaudio / phonon / gstreamer

the above diagram helped me understand better.

this website was helpful too.

overall, sound now works ( playback ) for all my mp3 and youtube etc.
