Same here. Just installed Ubuntu 14.x LTS to avoid issues with my Broadcom 43142 (I tried Fedora first.
This is a less-than-a-week old Asus X555LN that had W8.1 installed from factory and completely removed from the Hard Drive. * Secure Boot has been disabled. * No dual boot here. * Sound worked fine in Windows 8.1, Fedora 22 (unfortunately, WLAN did not and that's why I decided to try this Ubuntu LTS) and Windows 7 (I decided to try W7 just to do a Dual Boot but then I desisted and installed Ubuntu). * Sound works fine through headphones. * Toggling between speakers and headphones does not resolve the issue. * doing $ alsa force-reload does not resolve the issue. * Disabling auto-mute via $ alsamixer does not resolve the issue. $ lspci | grep Audio shows 00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b) 00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04) $ pulseaudio shows E: [pulseaudio] pid.c: Daemon already running. E: [pulseaudio] main.c: pa_pid_file_create() failed. Still looking for any additional information/entries at forums/tuts to try. Please advise if this thread will be followed up on and if we can expect any resolution.

I have personally tested a pair of earbuds to make sure that sound could play through the headphone port, and that isn't a problem. The sound driver just refuses to recognize the existence of the speaker, even though the kernel does. I wouldn't be surprised if the last upstream update had something to do with it.
