Public bug reported: 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://ubuntuforums.org/showthread.php?t=616845 None of these makes a difference. Regardless of the chosen model name, I get the following warning in /var/log/messages: hda_codec: Unknown model for ALC269, trying auto-probe from BIOS... Any ideas what might be causing this bug?
