Hi there, I am on an Thinkpad R31 and no sound after hibernation / resume. See attached lspci -vv. Im running the latest updates of today and kernel generic 2.6.24-18 and module snd-intel8x0.
The solution with restarting alsa-utils or "alsa force-reload" works, but only __after__ I logged into the session. Restarting alsa-utils however does not force to shutdown associated programs like the sound- applet ;) Putting this into the "/etc/acpi/resume.sh" (or other relevant files during resume) has NO effect (!!! very strange !!!). When the machine suspends, I hear a knocking sound when the sound shuts down. Same on resume. I hear the same knocking sound when I manually do a "force-reload" of alsa. But only a reload of alsa after logging in has success getting sound working. I searched and found according bug #151111 (HP Laptops), bug #11149 and bug #223742 (Serval Performance - fixed with module options snd-hda-intel model=toshiba). But description for the fix of the bugs is neither not applicable for thinkpads nor valid (links are dead for released fixes). After hours of searching about hardy and hibernation I found out, that ubuntu hardy uses pm-utils for this purpose which relevant directories are "/usr/lib/pm-utils/sleep.d" and "/etc/pm-utils/sleep.d". So I put a file called "80alsa" into "/etc/pm-utils/sleep.d" (see attachment) reloading alsa-utils and now (at almost 2 o'clock) my sound worked after resume ;) This leads me into some general questions: 1. Why do the acpi helper script do not work like expected? Are they used anyhow? 2. Has "/etc/default/acpi-support" any effect? 3. Would not be a global solution reloading alsa-utils better, than fixing each driver with an alsa-base module option? Hope this helped. Good night. ** Attachment added: "lspci-vv.txt" http://launchpadlibrarian.net/15222451/lspci-vv.txt -- [hardy] After suspsend sound isnt working anymore https://bugs.launchpad.net/bugs/198218 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
