I can confirm the same issue with a Toshiba Satellite P50t-B and Realtek ALC284. I had no sound coming from internal speakers, but there was sound from the headphone jack. I followed the instructions described by Fernando, and the daily ALSA update package fixed the problem. Thanks for posting about this! I'm running Ubuntu 14.04.2 LTS, and the issue occurs on this version too.
A few additional points worth mentioning. The ALSA daily build snapshots (https://code.launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa- daily/+packages) are a bit confusing. I used the 14.04.1 LTS version, which is titled, "oem-audio-hda-daily-lts-utopic- dkms-0.201503191631~ubuntu14.04.1". The series is "Trusty" and listed under 14.04.1, but it's name is "lts-utopic"? I'm assuming this should be "lts-trusty." Also I notice today that there is a .deb package accessible from the main Audio Develpment Team page for 14.04 LTS. This was not the case a couple of days ago. At that time, the build status was shown as a red "X", since new packages are not built daily for every release. For others dealing with this issue, it might be necessary to look through the completed builds list (https://code.launchpad.net/~ubuntu-audio- dev/+archive/ubuntu/alsa-daily/+builds?build_state=built) to find the most recent successful build for your version. One final comment is there seems to be a conflict with the ALSA update and VLC, or possibly PulseAudio and VLC. If VLC is installed, I lose the ability to control volume from the keyboard. It is still possible to make volume changes from the audio menus and screens. If VLC is removed, ability to control volume from the keyboard returns. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1398971 Title: [SATELLITE P50t-B-112, Realtek ALC284, Speaker, Internal] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1398971/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
