I see this also on my HP EliteBook 8530w laptop. In my case the changing color of the LED has helped me diagnose another issue.. my sound card seems to be sleeping at irregular times and waking up randomly. Sadly the times it wakes up does not seem even slightly related to when I'm trying to play sounds. I'll be filing a new bug about that soon.
Anyway, the reporter and I seem to be using the same (or very similar) audio controller: Codec: Analog Devices AD1984A Address: 0 Function Id: 0x1 Vendor Id: 0x11d4194a Subsystem Id: 0x103c30e7 Revision Id: 0x100400 I think this is an issue in how the driver handles our particular card. I've attached my complete info from the alsa project's alsa-info.sh script. ** Attachment added: "alsa.txt" http://launchpadlibrarian.net/35034672/alsa.txt -- alsa power-saving ambarass my laptop's mute led https://bugs.launchpad.net/bugs/456769 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
