I can confirm that I have the exact same problem with the headphones jack. After a fresh reboot it continue to work after a suspend-to-ram /wake-up cycle, but after sleeping/waking the second time it stops working. I find it curious that it works at all (after the first cycle) rather than just either working or not working at all.
My laptop is a Thinkpad X41 (non-tablet version). To be specific, I'm using the snd-intel8x0 driver, *not* the snd-hda-intel driver. Currently running Jaunty. Through searching I have found this: https://lists.ubuntu.com/archives /kernel-team/2006-March/000699.html There is no mention of *why* it needs to be blacklisted. Is it possible that due to changes in the past 3+ years this blacklisting is no longer necessary? At one point I pulled down the alsa source and trying to grok it for some sort of obvious error, but I couldn't make heads or tails of it. My suspicion is that this is a hardware/driver issue. The kernel isn't issuing any errors or warnings, so maybe after waking up the second time some module isn't sending the right messages/flipping the right bits with respect to the hardware? -- speakers are unmuted after resume from suspend while headphones are plugged in https://bugs.launchpad.net/bugs/101986 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
