Okay, so we can probably conclude that the audio is not working on Dell
Optiplex 380.
I'm not an expert on this just yet, but I'm writing down some notes of
what I can see:
First; According to Dell's datasheet, the codec chip is "ALC269Q", something I
don't see in the Linux sources. Also there is no sign of "dell" on alc269.
So my guess is that Dell Optiplex 380 is a relatively new computer, whose audio
has never worked on any Linux distro. Is this correct or has the same computer
audio working on earlier Ubuntu releases?
Looking at dmesg, I find this row: ALC269: SKU not ready 0x411111f0. I'm
not sure what SKU means, @Daniel T Chen, do you know? Anyway, it seems
to look at a specific widget node, which is probably a different node
for this chip, but I'm not sure what alc_auto_parse_customize_define
actually is supposed to do, and why.
Also, if I look at the codec proc file through codecgraph, I see that it
looks terribly misconfigured. One should take hda-analyzer and tweak
some settings to see if that actually makes things work.
** Changed in: alsa-driver (Ubuntu)
Status: Incomplete => Confirmed
** Summary changed:
- [Realtek ALC259] ALSA test tone not correctly played back
+ No sound on Dell Optiplex 380 (ALC269Q, probably new chip)
