 |
|
kernel konfig seems to be ok, as I can see the hdmi audio entry as follows:
| Code: |
lspci:
....
00:1b.0 Audio device: Intel Corporation 82801JD/DO (ICH10 Family) HD Audio Controller (rev 02)
....
01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde/Pitcairn HDMI Audio [Radeon HD 7700/7800 Series]
|
Also in alsamixer I can switch to HDA ATI HDMI from gpu.
| Code: |
and: aplay -l

Now when chosing Cape Verde/Pitcairn HDMI Audiio in kde5 plasma settings / multimedia there is no sound. I only get sound with internal analog HD Audio activated. Graphics via hdmi is working.
I also checked that tv and cable are ok by using my sons macbook to connect via hdmi and that one is able to send pic and sound to tv, so I guess cable and tv should be ok.
Please help me troubleshooting this, as it would be really cool to get sound over hdmi output on my tv.
All monitors are connected with minidisplay port adapters to dvi for the two monitors and minidisplayport to hdmi adapter for connection to tv. Monitors are connected at port 1 and 2 and tv is connected at port 4.

I have no mpv but had tried like this:
| Code: | aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav
Wiedergabe: WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate: 48000 Hz, mono |
and no sound was heard. |

good point, I am trying right now. Although I have no sound at all with gentoo livedvd, I see a difference here:
| Code: | cat /proc/asound/pcm

I was able to get soundooutput via hdmi on sabayon, which has similar output on cat /proc/asound/pcm as the gentoo livedvd had. Additionally I have found out, that it only works on ports 1-3 but not on the 4th port where I had connected my tv/hdmi before.
Now I am back on my system and trying to figure out, why I do not have these:
| Code: | 01-03: HDMI 0 : HDMI 0 : playback 1
01-07: HDMI 1 : HDMI 1 : playback 1
01-08: HDMI 2 : HDMI 2 : playback 1
01-09: HDMI 3 : HDMI 3 : playback 1
01-10: HDMI 4 : HDMI 4 : playback 1
01-11: HDMI 5 : HDMI 5 : playback 1 |
but instead I have | Code: | | 01-03: Generic Digital : Generic Digital : playback 1 |
only.

Check your radeon module parameters in /sys/module/radeon/parameters. Radeon have the audio parameter who must be set to 1 to have audio through Hdmi and the tv parameter who must be set to 1 too. I ever had an Amd/Ati video card and never been able to have audio through Hdmi.
Adapters can break the port (audio) capabilities.

| Thank you, I will check when I have access to my box. I was also afraid the adapter could be the problem, but as it works with livedvd of sabayon I am sure its a config issue. The main difference of my gentoo box is not having the hdmi devices as sabayon has, but only having a generic one so I thought the problem must be in a wrongly configured kernel. |

The audio parameter is set to -1 but I cannot change (not even as root) as the access rights on this file as it is set to -r--r--r--

Well I have everything compiled in kernel so no module unloading  I would first need to rebuild new kernel.
Can this be the reason why I only have a generic hdmi device while in a working configuration the device list looks different - see the aplay -l on the sabayon livedvd, where everything works as needed? |

| I always emerged radeon-ucode after emerge of gentoo-sources and as this is depricated now, I now emerge linux-firmware before building kernel, so I supose firmware is ok. |

Unfortunately firmware cannot load if the driver is built into kernel and the firmware is residing in /lib/firmware. For a very simple reason - the root filesystem is not mounted when kernel loads and nothing stored there can be accessed. Have you checked your dmesg for firmware loading?

I followed the suggestions in wiki:
https://wiki.gentoo.org/wiki/Radeon
So firmware is built into the kernel. Now when rechecking on the wiki, I see that even in the example of the wiki they see more than one hdmi device, I guess I must have limited my kernel somewhere. It is written: Other options there might be needed as well, e.g. don't set the number of soundcards too low, because even with one Radeon card alsa may detect more than one HDA ATI HDMI device, I am searching where I can set the number of soundcards now.. |

I finally found it 
Consulting the ALSA Gentoo wiki I have seen, that I had not set:
| Code: | Device Drivers --->
<*> Sound card support
<*> Advanced Linux Sound Architecture --->
[*] Dynamic device file minor numbers
(32) Max number of sound cards |
Setting these gave me the hdmi devices and with them - I now have hdmi audio |

Good job, Elleni :-)
It's always nice to see someone push through, and find the solution for oneself. |
