In 11.4 with my Intel High Definition Audio HDA Intel (STAC92xx Digital), I can no longer mute the sound via the mixer. You can't even turn the sound off with the Keyboard controls built into the laptop. The 11.2 sound system implements the LFE channel on this chipset. The Low Frequency Effects channel really does add a lot to the sound quality but neither the master Volume control or the Mute button controls the LFE channel. If you use LFE channel at all, you can't mute it or control volume in the normal way. So when you want to mute sound, you have to open the Kmix mixer and click two mute buttons. (The Alsa Mixer can't control the LFE channel at all). Anyone have a work around other than killing off the LFE channel? And where did the trebble / Base settings go in Kmix? This thing has taken a real step backwards in the last release. -- Explain again the part about rm -rf / -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
