alsa is only aware of the sound devices on the video card.
If alsa doesn't see a device, it won't work in pulse (or anywhere).
Alsa is the underlying access to the hardware.
So, is there any way that you have it turned off in the BIOS?
Is there a blacklist for the device in /etc/modprobe.d?
No.
Do an lsmod and an lspci, and check if the sound device on the
motherboard is mentioned there.
Not seen in lspci. A similar box has
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio
Controller (rev 02)
Run journalctl -r or journalctl -b, and do a search on snd_ ( /snd_) to
see if there was an error loading the driver for the motherboard sound
device.
Could you have caused an issue when you installed the new video card?
Bent something, loosened something, etc.
Access was difficult and the board
wasn't properly seated the first time
I powered up. Maybe.
Mythtv frontend setup sees ALSA:hdmi:CARD=NVidia,DEV=1, connected to the
tv, and it works. HDA NVidia, HDMI 1. Supports up to 2.0 (LPCM)
It also finds ALSA:hdmi:CARD=NVidia,DEV=0, with no connection detected;
and some Pulse options.
Possible loss of the non-hdmi options is inconvenient, but it seems
strange that vlc and smplayer don't work via hdmi when myth does. I'll
hunt for more settings.
