 |
|
Hello everyone!
I have a problem with sound over HDMI with DRM driver.
Any audio plays 2x or 3x speed and choppy(like it played piece of sound from buffer and wait new).
I can't google for it anymore, everywhere problems only with video or no sound.
Therefore here is my specs:
MSI Radeon HD4850 (DVI to HDMI adapter out of the box);
Kernel 3.11.3;
Mesa latest(FireBurn overlay);
PulseAudio.
Alsamixer shows only SPDIF for ATI HDMI device.
Any suggestions, please? |

So I rebuilt it back. |

Progressing.
Changed multimedia backend from phonon-gstreamer to phonon-vlc, now sound is choppy (via HDMI) |

Have you activate the audio radeon kernel module parameter option in the kernel command line for Radeon compiled in the kernel or in a conf file in /etc/modprobe.d/ directory for Radeon support in module:
| Code: | radeon.audio=1
options radeon audio=1 |
I tried to activate sound over Hdmi with Radeon free driver support. Like you Alamixer was only showing Spdif for Hdmi and I never been able to ear any sound from Hdmi.
I read that we must use Ati driver fglrx for that because the free Radeon driver audio support is limited. Have better information by your own search.

I have built-in kernel driver and passing radeon.audio=1 via grub command line.
As you see: sound is works, but pretty bad.
Searching for my own tells me that having only SPDIF out in alsamixer is OK. |

Could your DVI to HDMI conversion be a cause of your sound problem? Have you try DVI to DVI or HDMI to HDMI if you can? This idea just come to pass through my mind.

Okay! This time it all wraps up: I booted LiveDVD Calculate Linux with radeon.audio=1 option, and it is works there!
So, this is not a hardware problem. Need to look deeper into system... |
