I have checked many forums for several months and cannot find the fix. I have two sound cards, motherboard and hdmi. Only the hdmi gets detected by alsa. It is not good as I am only using the motherboard one. The dmesg shows "no codecs initialized" for the first card. ubuntu@ubuntu:~$ lsb_release -rd Description: Ubuntu 12.10 Release: 12.10 ubuntu@ubuntu:~$ lspci | grep -i audio 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) 01:00.1 Audio device: Advanced Micro Devices [AMD] nee ATI Caicos HDMI Audio [Radeon HD 6400 Series] ubuntu@ubuntu:~$ dmesg | grep -i hda-intel [ 97.691334] hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x000f0000 [ 98.692766] hda-intel: No response from codec, disabling MSI: last cmd=0x000f0000 [ 99.694197] hda-intel: Codec #0 probe error; disabling it...
