I have just installed Gentoo, according to the gentoo handbook. I am running systemd and I'm trying to get pulseaudio working. If I open up pavucontrol I only see the dummy output. On the Gentoo Wiki, it says this means I do not have proper permissions (but it's the same if I run pavucontrol as root). That article seems out of date, since the kernel ACL configuration does not work as described.
I have ACL enabled as far as I can discern:
| Code: | $ cat /usr/src/linux/.config | grep ACL
CONFIG_EXT4_FS_POSIX_ACL=y
CONFIG_FS_POSIX_ACL=y
CONFIG_TMPFS_POSIX_ACL=y
CONFIG_NFS_V3_ACL=y
CONFIG_NFS_ACL_SUPPORT=y
|
and I have the HD Audio drivers enabled too:
| Code: | $ cat /usr/src/linux/.config | grep SND_HDA
CONFIG_SND_HDA=m
CONFIG_SND_HDA_INTEL=m
CONFIG_SND_HDA_DSP_LOADER=y
CONFIG_SND_HDA_PREALLOC_SIZE=4096
CONFIG_SND_HDA_HWDEP=y
CONFIG_SND_HDA_RECONFIG=y
# CONFIG_SND_HDA_INPUT_BEEP is not set
CONFIG_SND_HDA_INPUT_JACK=y
CONFIG_SND_HDA_PATCH_LOADER=y
CONFIG_SND_HDA_CODEC_REALTEK=m
CONFIG_SND_HDA_CODEC_ANALOG=m
CONFIG_SND_HDA_CODEC_SIGMATEL=m
CONFIG_SND_HDA_CODEC_VIA=m
CONFIG_SND_HDA_CODEC_HDMI=m
CONFIG_SND_HDA_I915=y
CONFIG_SND_HDA_CODEC_CIRRUS=m
CONFIG_SND_HDA_CODEC_CONEXANT=m
CONFIG_SND_HDA_CODEC_CA0110=m
CONFIG_SND_HDA_CODEC_CA0132=m
CONFIG_SND_HDA_CODEC_CA0132_DSP=y
CONFIG_SND_HDA_CODEC_CMEDIA=m
CONFIG_SND_HDA_CODEC_SI3054=m
CONFIG_SND_HDA_GENERIC=m
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0

Our trusty friend lspci reports:
| Code: | $ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation NM10/ICH7 Family High Definition Audio Controller (rev 02)
02:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1)

How can I troubleshoot this?
Thanks for your time.
Bonus question: What is the difference between pulseaudio and alsa and oss, and why did it matter enough to implement three different systems "just" to play sound? |

OSS and Alsa are sounddrivers.
OSS is deprecated.
Pulseaudio is a format-changer. |
