Public bug reported: I report this bug just for information, cause it took me several hours to find out the solution.
--- System --- Description: Ubuntu 10.04.1 LTS Release: 10.04 Package: alsa-base 1.0.22.1+dfsg-0ubuntu3 --- Problem --- After installing Ubuntu 10.04 LTS on HP 625 Notebook, you won't get sound through the internal notebook speaker. Line-out works perfectly. The ALSA Information Script reports the wrong hardware: HDA-Intel - HDA ATI SB IDT ID 7667 That's because of the wrong alsa driver version, missing the newest drivers: Driver version: 1.0.21 --- Solution --- You need alsa driver version 1.0.23 or higher. To install at least driver version 1.0.23 at this time, take the following steps: * Activate the "Unsupported updates (lucid backports)" repository in Synaptic Package Manager (Settings -> Repositories -> Updates). * Reload your package information. * Install the package "linux-backports-modules-alsa-lucid-generic". This will also install a new linux kernel version. * Restart and your sound should work properly. * If not, raise all available volume levels in alsamixer (start alsamixer in terminal). Now the ALSA Information Script reports the right hardware: HDA-Intel - HDA ATI SB IDT 92HD88B1 Best regards Akaname ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New -- Hewlett-Packard HP 625: no speaker sound in Ubuntu 10.04 (Lucid) fresh install https://bugs.launchpad.net/bugs/606893 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
