I'm trying to fix the sound on some Dell Optiplex machines, which are running the ALC269 chip. I can "fix" them with some hda-verb commands, but that won't get me auto-mute, so I'll have to make a model (or possibly more than one) for them.
What is actually a problem?
It varies between the different models, but most problems I think come from that pin NIDs aren't the same as the auto-parser (or any of the models) assume.
This causes playback, recording, auto-mute etc to fail.
In addition, a minor issue is that one of the models are being mislabeled as ALC259.
Anyway, I have a pair of questions:
- In dmesg, there is a "SKU not ready" message at startup. What is SKU,
and is it a problem that it is not ready?
Realtek codecs suppose that the device PCI SSID is set up for indicating hardware functionalities. This is Realtek-specific, and most vendors don't follow. The driver spews some messages when the SSID isn't compliant.
- There are two DACs, and all models so far seem to use NID 0x03 for
headphones and NID 0x02 for everything else. But is there a single stream going through the controller and then splitted into two on the codec side, or is just one of the DACs activated at a time, depending on the jack sensing state?
Both DACs use the same single stream at the same time.
Thanks for your answers!
