what i've tried

i've tried (among other things):

• all obvious stuff (headphones working, alsamixer not muted, etc)
• making sure audio device enabled in bios
• toggling front audio in bios between ac97 & hd
• installing realtek drivers site.
• adding "options snd-hda-intel model=auto" & other models /etc/modprobe.d/alsa-base.conf
• https://wiki.ubuntu.com/audio/upgradingalsa/dkms
• disabling / enabling loopback & automute in alsamixer
• using multiple built-in audio profiles in pavucontrol
• using multiple ports in pavucontrol
• using 1 of latest kernels new alsa driver
• reinstalling alsa & pulseaudio

• killing pulse daemon , testing sound with:

  aplay -d plughw:0,0 /usr/share/sounds/alsa/front_center.wav

  speaker-test -c 2 -t wav

• renaming /etc/modprobe.d/alsa-base.conf make alsa use defaults

• disabling jack detection hdajackretask
• retasking rear green line out other options hdajackretask
• testing sound output fresh windows install (which worked...)

pulse errors

i noticed think causing this, can't find relevant solutions on web.

pulse logging thousands of messages in debug mode.

nov  1 17:09:44 synapse pulseaudio[2445]: [alsa-source-alc892 analog] alsa-source.c: overrun! nov  1 17:09:46 synapse pulseaudio[2445]: message repeated 10 times: [ [alsa-source-alc892 analog] alsa-source.c: overrun!]

i've been debugging issue 2 days now. first problem ubuntu have not been able solve myself.

any advice appreciated. when need more information system, please ask.

i had same problem. first time did upgrade 14 lts 16 , surprise, no sound. after new installation without results default.

the next steps work me:

1. open terminal , type alsamixer, card hda ati sb chip realtek alc892, turn auto-mute disabled.
2. after i'd install pulse audio volume control.
3. open pulse audio volume control , in configuration tab can see ati hdmi digital setereo , internal audio. select internal audio: stereo analog duplex (estéreo analógico duplex).
4. in pulse audio volume, select ouput devices, , internal analog stereo select: analg headphones.

important: must have installed ati drivers first. d atonaltzin
