Re: [Bug 80893] Re: [Feisty] Inaudible audio upon resuming from suspend-to-disk
One more bug to check for workarounds: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/270593 logging out, (killing pulse-audio) followed by alsa force-reload re-instates sound. I'd also try suspend/resume by starting Ubuntu 9.10 from the liveCD (installation cd). That's how you can check if some config file from older releases causes the problem. I previously had that problem but I cannot remember how I fixed the problem (reinstalling acpid , acpi-support, alsa-base or something like that). -- [Feisty] Inaudible audio upon resuming from suspend-to-disk https://bugs.launchpad.net/bugs/80893 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: [Bug 80893] Re: [Feisty] Inaudible audio upon resuming from suspend-to-disk
weird, shmi85, on my T60 HIBERNATE_MODE=platform does the trick, and many other success stories come from thinkpad owners. first, I would try the unpatched kernel, for which Guilherme Salgado has built a deb package (link above in this thread): download http://rookery.ubuntu.com/~kyle/kernels/salgado/2007-04-25/linux-image-2.6.20-15-generic_2.6.20-15.28_i386.deb go to the download location in the shell, and issue the command $ sudo dpkg -i linux-image-2.6.20-15-generic_2.6.20-15.28_i386.deb pretty easy, thanks to Guilherme. since you state thate your sound problem are not fixed by a hard shutdown, I would also check if the settings of the sound card are screwed up (no sound could come from a muted channel, and hiss from a feedback due to the microphone input too loud and not muted). just issue $ sudo alsamixer play around with the levels and see if anything changes. cheers m On Tue, 2007-06-26 at 04:35 +, shmi85 wrote: Just an update on my Thinkpad R52 running Fiesty. As stated earlier, I tried this fix: HIBERNATE_MODE in /etc/default/acpi-support to: HIBERNATE_MODE=platform as requested by csd. Unfortunately, although it worked for two days, I suspended the machine earlier this afternoon (power-saving mode rather than the powered down shutdown or whatever of hibernate) and now the sound is no longer working, even after a completely shutdown and restart. In addition, occasionally I'm getting an extremely high pitched feedback-like whine from the machine and quieter and lower in pitch whines slightly more frequently, usually when I move the laptop but not always. In the acpi-support file, there's a line refering to the suspend function and changing it from S3 to S1. I'm assuming that has something to do with amount of power conserved and I was hesitant to fiddle with it because I really have no idea what changing the values does. I'd like to try using the unpatched kernel, since it seemed to work for a lot of people, but I'm very new at running a new linux system and I don't know how to compile and install a new kernel while leaving the rest of the system (GUI settings, etc) unchanged. If anyone's willing to help me out with the specifics of this operation, please feel free to email me at shmi85 at yahoo dot com.

Re: [Bug 80893] Re: [Feisty] Inaudible audio upon resuming from suspend-to-disk
That's correct; the bug has been fixed upstream, but I didn't have the time to track down which specific revision fixed it so that we can ask somebody from the Ubuntu Kernel Team to cherry pick it, so I guess we'll have to wait because reverting the commit which introduced this bug may cause suspend to break on other machines. -- [Feisty] Inaudible audio upon resuming from suspend-to-disk https://bugs.launchpad.net/bugs/80893 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've reported it on the linux-acpi mailing list [1] and to the patch's author, but nobody replied so far.

Re: [Bug 80893] Re: [Feisty] Inaudible audio upon resuming from suspend-to-disk
That's right. I already identified the merge in which the regression was introduced (it's a merge from linux-acpi-2.6 between 2.6.20-rc1 and 2.6.20-rc2). I have only a few commits left to test before I can pinpoint the right culprit. -- [Feisty] Inaudible audio upon resuming from suspend-to-disk https://bugs.launchpad.net/bugs/80893 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 80893] Re: [Feisty] Inaudible audio upon resuming from suspend-to-disk
In my case (a T60) just a shutdown is enough. Restarting doesn't help, though. -- [Feisty] Inaudible audio upon resuming from suspend-to-disk https://bugs.launchpad.net/bugs/80893 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
