Audio works on internal speakers and headphones using card 1 (HDA Intel PCH). But pavucontrol will let me choose HDMI even though it appears under "aplay -l" and under /proc/asound things look ok to me.
Also note: this is a laptop on a Thinkpad Ultradock with the HDMI plugged into the dock. I note that alsa driver does not detect the audio line out on the dock and there is no way to play through that channel. I'm not sure that this is related, but perhaps has to do with some lack of support for the dock?

I meant to say: pavucontrol will NOT let me choose HDMI as output. Sounds can not be routed to HDMI. I tried "aplay -D some_sound.wav" for all channels in the "aplay -l" list. Only PCH works.
