Also affects me on Lucid alpha 2010-04-13 daily build (obtained by testdrive, but testing on real hardware from USB drive). Sound works perfectly in Karmic on this laptop (Msi Wind U100, ALC1200 codec).
Neither internal speaker nor headphones work. Sound preferences detects "Internal Audio 1 Output / 1 Input" in Analog Stereo Duplex mode. But Input tab shows no cards and all controls are greyed out, and Output tab shows only Dummy Output. alsa-info.sh output at http://www.alsa- project.org/db/?f=627a0bcabcf5d3887d8eb5663920cb1ae1473269 Interestingly, when I attached a USB audio (which works on karmic), it also didn't work! Hardware tab is listing a new audio headset. But Input tab is still empty, and Output tab still shows only Dummy Output! How should I proceed with testing? - apport-collect? attach System Testing ("Checkbox") report? - install linux-backports-modules-alsa-2.6.32-20-generic and reboot? [I also have "hda_codec: ALC1200: BIOS auto-probing." in dmesg, but is this advice still relevant?] - provide any information for comparison from Karmic where it works OK? - try newer Lucid image? [is there an faster way to update a USB stick than Startup Disk Creator again?] ** Tags added: lucid -- No speech is not comming out on during system test program on msi wind u100 https://bugs.launchpad.net/bugs/458746 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
