[Ron <rshimshock@xxxxxxxxx>]

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.
