Hi jadedcyborg,
I stumbled across an Ubuntu bug about the 3.10 kernel and Logitech wireless devices. It looks like they've got a handle on that particular issue, at least.
I've noted the HDMI audio issue you're experiencing-- I'll address that later, unless the wider community beats me to the punch.
Cheers
Hi!
I've been pulling my hair for some days now trying to get my new Haswell-based Ubuntu HTPC to output audio via HDMI.
I'm using Ubuntu 13.04 with allt the latest updates from the official repositories. I've been trying all different configurations to try to get it to work. With the default install, the Intel HDMI Audio device shows up properly in '§ lspci ' and in '§ grep "Codec:" /proc/asound/card*/codec* ', but not when running '§ aplay -l '. It doesn't show up in ubuntu standard sound settings nor in pulseaudio settings. Running '§ lsmod | grep hda ' shows the driver is loaded but for some reason the device still doesn't show up. I've tried disabling, reenabling the sound device(s) in UEFI but still no luck. I've tried updating the ALSA drivers but still no difference.
Until...
When I updated to mainline kernel 3.10, the HDMI audio device shows up in the settings as expected and works, although only in stereo mode (in 5.1 mode the sound crackles and don't come from the correct speaker). Only problem is (pretty big one) with the 3.10 kernel my Logitech Wireless keyboard/thouchpad combo doesn't work, at all.
I'm starting to understand the expression "Linux is only free if your time has no value"...
Please help, I'm completely out of ideas on this one.
And no, I don't want to buy extra cables to use analog/optical instead for two reasons: 1. It's very inconvinient to access the cables behind my A/V-reciever; 2. I shouldn't have to. This should work, it's 2013 ffs...
