Korora laptop / Trisquel 7 audio not working

Hi, I have Trisquel 7 netinstall installed on a ThinkPenguin Korora laptop.
nik@Penguin-Korora:~$ lspci|grep Audio
00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 09)
00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04)
I can't hear any sound when watching webm videos in Abrowser, and I've made sure the channels in alsamixer look good. Strangely, there is no "PCM" channel in alsamixer .. could this be the issue? If so, how do I solve it?
When I try to play an mp3 with VLC, I get this error:
nik@Penguin-Korora:~$ cvlc music/fade.mp3
VLC media player 2.1.4 Rincewind (revision 2.1.4-0-g2a072be)
[0x2670978] pulse audio output error: PulseAudio server connection failure: Connection refused

Should I install pulseaudio? If so, is there any setup I need to do to get audio working?
I would install the "pulseaudio" package and see if it "just works". However, with the proper configuration, I believe you can get sound with ALSA only.
Thanks for your help. I was able to figure it out without pulseaudio - I just had to reconfigure VLC in the settings menu to use the correct sound card. Now I need to find out how to get audio to work for videos in Abrowser.
