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) -- No sound on Dell Optiplex 380 (ALC269Q, probably new chip) https://bugs.launchpad.net/bugs/582199 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
