[LINUX]No sound on 22kHz Flash files through hdmi - martdj - 2010-12-20
I've been upgrading my HTPC lately and this is the only thing that doesn't work. I'm using XBMC 10.0 on a Lucid minimal installation. I'm using a mainboard with a nvidia 9400 chipset. nvidia drivers: 260.19.26
Multichannel audio is working fine. Everything is streamed through HDMI. My settings in the System-Audio screen are "hdmi" for all 3 items.
Whenever I try to play any flash file (like a youtube movie) with 22kHz sound, the video is very slow (could be half speed but feels slower) and I have no sound at all. If I change the settings of system-audio to hdmi-default-hdmi, the video playback is normal speed but I only have navigation sounds left in XBMC.
My .asoundrc file for the xbmc user looks like this:
Code:
pcm.dmixer {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0660
slave {
pcm "hw:0,3"
rate 48000
channels 2
format S32_LE
period_time 0
period_size 1024
buffer_time 0
buffer_size 4096
}
}
pcm.!default {
type plug
slave.pcm "dmixer"
}I also tried these settings, but that didn't make a difference

}Does anyone have any idea how to fix this issue? I guess it has to do with my alsa settings somwhere, but I wouldn't know what to change how

ok, going to bump this one. I found out that the slow playback is caused by a bug in Dharma. Setting my audio to 2.0 fixed that problem, but still no sound. However, if I select Digital and IEC958 as settings to use my spdif cable instead of the hdmi cable for the sound, I do have sound in those files. This regretfully breaks my multichannel music, so this is not a real solution. Does anyone recognize this and know how to fix it?
