Description

Hi,

since I migrated from nvidia drivers (blob) to nouveau quite a while ago (several months) I have those really annoying disruptions for some seconds. I first thought it might be the driver but e.g. XBMC/Kodi works quite fine. It's a IONITX (2nd gen) using the HDMI of the GPU.

Not sure if that is related:
kernel: [ 1080.248049] snd_hda_codec_hdmi hdaudioC1D1: HDMI: audio coding type 0 not expected
kernel: [ 3217.198035] snd_hda_codec_hdmi hdaudioC1D1: HDMI: audio coding type 0 not expected

Is there anything I can do to help to get that debugged and fixed? I have no idea about those sound things.

Damn, forgot to login again...
Anyway, what I also forgot was to mention that playing recordings works fine as well. So it's just live TV it seems.

Try to set the audio buffer higher.

/etc/vdr/setup.conf: softhddevice.AudioBufferTime = 600

Or setup -> softhddevice -> audio -> buffer time = 600

Check if the hardware decoder is used. Syslog helps to see what happens.

Setting the buffer to 600 had no effect at all. I'll try to figure out the decoder being used later today.
So to summarize it again:
Recording works, no disruptions or so
Playing recorded videos works fine as well
Only live TV is affected
Setting the "AudioBufferTime" to e.g. "600" had no effect at all.

Tried to figure it out but there was nothing specific so far. Can you be more specific?

I also got those disruptions while playing recorded Videos. :(
