hdmi audio works with windows2go so hardware ok

I tried this suggestion but no luck (intel_iommu=on,igfx_off ):

did you find your hdmi tv/monitor's EDID in xorg.log ?

xrandr --verbose

When I plug in the HDMI I get this in dmesg:

This is what I see in my audio settings when I connect the hdmi cable and try to get sound on my tv.

Ok. How do I fix that?

[trendzetter (trendzetter)]

Or does this mean either my tv or cable is faulty? It seems to me that it can't be that bad since I was able to play sound using windows2go.

the driver need to know the capability of your hdmi tv/monitor (e.g. speakers arrangement , channels and formats , DTS, AC3, ....)

Raymond, EDID is normally also used to determine the screenresolution but that seems to have a working baseline configuration. I also play hdmi video + audio on my older laptop with intel hdmi with the same cable and tv. It's a sony bravia kdl 32ex600. I will try to install the firmware update. I will let you know soon.

[trendzetter (trendzetter)]

The older laptop is also running ubuntu 13.10 btw so the only difference is the intel chipset controlling it. Both periperals and the OS is the same.

[trendzetter (trendzetter)]

On the old with working hdmi audio I have got this:
$ uname -a

In windows I copied the EDID of the intel haswell laptop without audio over hdmi on ubuntu.

it is the graphic driver which send request to your hdmi tv/monitor to get EDID, it extract info from EDID to ELD and pass ELD to audio driver

are you connect your TV to display port , hdmi or DVI connector ?

The file is located in /proc/asound/cardX/eld#Y.0 (where X is the card number, and Y is the device number starting from 0. So if aplay -l shows Card 0, device 3 as being the first device listed you need to check /proc/asound/card0/eld#0.0).

[trendzetter (trendzetter)]

With the HDMI cable connected I get this:

GOOD news!! I found a workaround that could be useful for others with the same problem as well as for finding the cause/solution.

I noticed that I do get audio over hdmi when I close the laptop with the hdmi cable connected. It then goes to sleep. When I open it the audio over hdmi magically works!

Is there any details I can post for the ubuntu devs so they can find out what causes this bizarre issue?

[Raymond (superquad-vortex2)]

are you using latest alsa driver ?

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/log/sound/pci/hda?qt=grep&q=haswell

[trendzetter (trendzetter)]

Raymond,

I am currently on the mainline 13.10 kernel. Should I try to install a kernel from the alsa team ppa to test if I get audio correctly all the time with the new versions?

Do your other computer HDMI suppoft 8 channel LPCM or stereo ?

[Raymond (superquad-vortex2)]

For digital audio, if an HDMI device supports audio, it is required to support the baseline format: stereo (uncompressed) PCM. Other formats are optional, with HDMI allowing up to 8 channels of uncompressed audio at sample sizes of 16-bit, 20-bit and 24-bit, with sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz and 192 kHz

if your other computer only support stereo, they don't need any speaker allocation
