Here we go again! Whislt playing a video through Videos with the sound playing over the speakers, I turned on a pair of Bluetooth hadphones. Sure enough, the headphones' menu item appeared in the Systems Settings > Souund pane. I needed to hightlight the item to get the sound through the headphones. I then turned off the headphones. The headphones' menu item disappeared and the Speakers item was highlighted. However, there was no sound through the speakers. Even clicking on the menu item failed to produce any sound.
Plugging a pair of wired headphones caused their menu item to appear but no sound at all, even after clicking the menu item. I can only assume that the sound system had crashed! I did a restart and got the sound working again. Unfortunately, the system is still unstable. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1402666 Title: [XPS13 9333, Intel Haswell HDMI, Digital Out, HDMI] Playback problem Status in alsa-driver package in Ubuntu: Incomplete Bug description: If an HDMI monitor is plugged into the video out and the Videos app is started, the Systems Settings > Sound > Output shows only the Speakers, Built-in Audio in the Play sound through listing. The HDMI option is not presented. The workaround is to open the VLC app which lists the Built-in Stereo (HDMI) option under its Audio > Audio Devices menu. When a video is started in VLC, having selected the HDMI option, the sound plays through the monitor speakers. The HDMI / Display Port , Built-in Audio item then appears in the Play sound through window, even though the selection highlight remains on Speakers. The sound output can be switched between either output by highlighting the chosen option. If VLC is closed and Videos is restarted, the sound now plays through the previously selected HDMI item and can be switched between the monitor and the laptop's speakers. What I regard as a bug is the failure of the HDMI option to appear in the Play sound through listing as soon as an HDMI monitor is plugged into the Display Port output. Obviously, VLC has the means to add this item but the Videos app does not seem to be able to do this by itself. In contrast, as soon as a previously paired set of Bluetooth headphone are turned on, the Headset does appear as a menu item in the listing. I would reasonably expect the plugging in of an HDMI monitor into the Display Port to automatically add this item as well as its affects on the Screen Display pane of Systems Settings. Note: the laptop is running Ubuntu 14.10 and the Linux kernel has recently been upgraded to v3.18 (Vivid).
