Ubuntu 13.10 installed fresh (not upgraded) on an Intense PC (Analog and S/PDIF share same jack)
Analog audio output used to work just fine, but now does not appear in sound settings anymore; only "Digital Output (S/PDIF) Built-in Audio" is shown. I never used S/PDIF output; maybe it works, but it's currently useless for me - If I choose it, nothing goes to the speakers.
aplay -L shows
default Playback/recording through the PulseAudio sound server sysdefault:CARD=PCH HDA Intel PCH, ALC888 Analog Default Audio Device front:CARD=PCH,DEV=0 HDA Intel PCH, ALC888 Analog Front speakers (...)
playing to these devices with
aplay -D <device> /usr/share/sounds/alsa/Front_Center.wav:
- "default" - everything is silent.
- "sysdefault" - sound plays to the speakers normally (HW is OK!).
For any other device I get an error
aplay: set_params:1239: Channels count non available
I've found a partial workaround: I installed pavucontrol, and from its configuration tab I can choose "Analog Stereo Sutput" and then all applications play audio normally (including aplay to "default"). But, there is still no "analog output" option in the system settings (only S/PDIF), and no audio control in the menu bar; I have to do everything from pavucontrol.
