Mageia forum

Hi,
I've Mageia 2 installed on my Acer 5730 laptop and as in topic I have no sound coming from HDMI output. In order to exclude any hardware issue I've checked HDMI connection to my TV set under Windows 7 and in this configuration I have not any problems, video and audio as well were played. What was done till now:

- in alsamixer I unmuted all digital channels;
- using aplay -D command I have checked all audio hardware devices without effect, no sound through HDMI in all cases but in one - hw=0,3 I hear sound through optical jack;

some debugs:

Code: Select all

cat /proc/asound/modules
 0 snd_hda_intel

Code: Select all

[root@localhost tonny]# lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

Code: Select all

root@localhost tonny]# aplay -l

Would you give me some advices?

Try using pulseaudio volume control. (mixer) Should be on menu, sound and video.

the problem is related to the nvidia graphics driver. maybe you'll find a solution here: http://www.silicondust.com/forum/viewto ... e386c0e703. afaik is this problem resolved in the 304 nvidia driver.
