![]() Rather, the way to resolve this issue is to add an option to PA Prefs to enable or disable Powersave mode and to set the delay time and have this option disabled by default. Therefore, I believe the best way to resolve this issue is not to remove the powersave feature, as it can be an important feature for netbooks and laptops. It is a hardware issue caused by powering up the sound circuitry. ![]() At least, it's not a software bug, and it's nothing that Ubuntu can control or fix. I don't think the popping/clicking when the sound card is being woken up is a bug. I then restarted Pulseaudio (killall -9 pulseaudio, and let it respawn), and now the light stays blue, and there's no more popping or clicking when a sample is played. So, I went into /etc/pulse/default.pa, found the following line:Īnd commented it out. This leads me to believe that the light turning orange in Ubuntu is actually indicating that the sound card is being powered off. You can also fade-in/fade-out audio by dragging the top-left and top. In fact, if I mute the sound either through the button or through the speaker icon in my notifications area, the sound mutes, but the light stays blue. Change the audio level of a track by sliding up/down the dotted line of an audio track. Now, although this mute button light works as it should in Windows, it has never worked properly in Ubuntu. The next sound played after that would turn the light blue again, but would also make a loud "pop" sound when the light changes, and I'd notice the first half-second or so of the sound would be clipped off. I have an HP Pavilion dv9830 laptop, and noticed that the light in my keyboard media strip's mute button would turn from blue (supposed to indicate not-muted) to orange (supposed to indicate muted) about 15 seconds after the last sound has played. I had this problem, but I managed to fix it by a rather different approach than the workarounds already posted here.
