Hi, I just got a new laptop in the Asus K series. I've installed Xubuntu on it and the audio only works through the headphones even though pulse audio says it's playing. Prior to installing Xubuntu, I ran a OpenSuse, Debian and Backtrack live disks and none of them had sound either. Here are some outputs that might be helpful. lspci | grep Audio 00:03.0 Audio device: Intel Corporation Device 0a0c (rev 09) 00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04) cat /proc/asound/card1/codec* | grep Codec Codec: Realtek ID 233 cat /proc/asound/card0/codec* | grep Codec Codec: Intel Haswell HDMI A few of the things that I've done are to reinstall pulse and alsa. I checked to see if alsa was muted. I added a few different lines to the /etc/modprobe.d/alsa-base.conf file. I've also played around with the settings in pulse. Any help would be much appreciated.
