[Bug 445889] Re: no sound from integrated speakers (Realtek ALC269, snd-hda-intel driver)

[Arwin Tugade]

Well I just got a Sony Vaio VPCEB15FM and I have the same problem of the
card being detected but no sound from the speakers or headphone jack.  I
tried the module option but none of them fixed my issue.

$ aplay -l

There is this tool that lets you flip settings around but the changes
aren't persistant: http://www.alsa-
project.org/main/index.php/HDA_Analyzer

To get my speakers working, I ran the hda_analyzer above and under
"Node[0x19]" at the bottom in a pane called "Widget Control", I flipped
the VREF to "HIZ" and that did the trick.  Because I'm impatient, I
flipped this value in the kernel source tree I'm using (stable
2.6.33.2):

<KERNPATH>/sound/pci/hda/patch_realtek.c

13479c13479
<       {0x19, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_VREF80},
---
>       {0x19, AC_VERB_SET_PIN_WIDGET_CONTROL, PIN_IN},

Recompiled and it's persistent.  This is just informational and is by no
means a official solution, so use it at your own risk, I just wanted to
get this out of the way so I can get on to using my laptop.
