nss: Reading through the sound test results I found an entry that hints about a bad bios: [ 1.000693] ACPI: BIOS _OSI(Linux) query ignored [ 1.024327] ACPI Error (psargs-0359): [\_PR_.CPU0._PPC] Namespace lookup failure, AE_NOT_FOUND [ 1.024335] ACPI Error (psparse-0537): Method parse/execution failed [\CPUT] (Node f701c150), AE_NOT_FOUND [ 1.024378] ACPI Error (psparse-0537): Method parse/execution failed [\PSSC] (Node f701c168), AE_NOT_FOUND [ 1.024419] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_._REG] (Node f702f3c0), AE_NOT_FOUND [ 1.024474] Fail in evaluating the _REG object of EC device. Broken bios is suspected.
I don't think its necessarily relevant to this issue, but it might be worth checking if there is a bios update availible. I've also found a number of different suggestions of things to try googling around (For example: http://ubuntuforums.org/showthread.php?t=444126), but nothing for you particular laptop. -- laptop speakers doesn't work https://bugs.launchpad.net/bugs/581088 You received this bug notification because you are a member of Registry Administrators, which is the registrant for ALSA driver. _______________________________________________ Mailing list: https://launchpad.net/~registry Post to : [email protected] Unsubscribe : https://launchpad.net/~registry More help : https://help.launchpad.net/ListHelp
