Bug Description
I'm using a brand-new Acer AS1410 notebook/netbook, with Ubuntu 9.10 Netbook Remix. The manufacturer reports the audio chip as Realtek ALC269, although lspci says it's an Intel ICH9 HD Audio Controller (pci id 8086:293c).
With the snd-hda-intel driver, configured for analog output, the sound card works correctly with headphones plugged in. However, with no headphones plugged in, there is *no sound* from the integrated speakers.
This includes the PC speaker beep. I modprobe pcspkr and try to get a beep, and there's nothing.
I know that the internal speakers work fine under Windows Vista Home Premium with the supplied drivers from Realtek.
I've tried some of the suggestions about tweaking the model parameter of snd-hda-intel module: http://
hda_codec: Unknown model for ALC269, trying auto-probe from BIOS...
Any ideas what might be causing this bug?

Well... after playing around in Linux for a while, trying to get the internal speakers to work, I went back to check the Windows settings. And *now* the internal speakers don't work in Windows either. Verrrry strange. I tried a hard reboot, tried removing and reinstalling the battery, tried reinstalling the Realtek Audio drivers in Windows... still nothing.
Is it possible that this hardware stores some state in NVRAM or something like that, which neither Windows nor Linux driver normally accesses??
