 Posted: Thu Jul 11, 2002 8:02 pm Post subject: KDE3 Kmixer and Amixer have no effect on sound volume |
 |
|
Hi all.
I have just installed my first Gentoo Linux system based on the 1.3b file (for GCC 3.1) along with KDE 3.02 and Alsa 0.9.0-rc2. However, I noticed none of the controls (volume, mute, bass, trebel) in either KMixer or Amixer has any effect on the sound output. Therefore, if I want to change volume, treble, or bass, I need to rely on the internal equalizer provided by the media player used.
I did not see any error message when running either KMixer or Amixer. My sound card is a SBLive 5.1 Platinum and I uses its SPDIF line ouput with a external receiver.
Does anyone know what may be wrong with my system setup?
Thanks. |

| Mmm, do you have the module pcm-mixer-oss loaded? That might do the trick. |

What permission is /dev/mixer supposed to have?
I don't remember the permission right now but I'll check when I get home. |

Are you a member of the audio group? type groups in a terminal to find out (if you don't already know).

Yes, the non-super user login I use is part of audio group. Sound file playback is fine using both root and my own personal login. I know if the login for non-super user is not part of audio group, you can't hear sound at all. My problem is I can't change sound volume, bass, treble, and other channel settings. I am stuck with the default settings which I'm glad did not mute my master or PCM channel. |

check your /etc/defsd.conf
make sure the lines from the destop config guide are in there...and spelled right.

After playing with the alsamixer, it appears that it is working for some of the controls. I can adjust volumes for headphone, wave output, aux line-in 2.
But I still don't know why the master volume control has not affect. Line-in 1 (on the back of SBLive card) appears to be muted and I have adjusted all the controls and nothing seems to work so I had to use the aux line-in on the LiveDrive itself.
Does any owner of SBLive 5.1 Platinum knows which alsamixer control will change the volume for line-in 1?
Thanks. |

I find that I have to
amixer set MASTER 100 unmute
amixer set CD 100 unmute
amixer set PCM 100 unmute
every time I log in so I presume you would have to do somthing like
amixer set LINEIN 100 unmute
to unmute the line in.
Maybe someone knows the correct command instead of LINEIN? |
