Hello Takashi !
I tried to apply the patch that removes restrictions to 16bits 48khz format. Well now we have the following: 16bit 48khz works 32bit 48khz works 32bit 44khz, 96khz, 192khz don't work 24bit 44khz, 48khz, 96khz, 192khz don't work 16bit 44khz, 96khz, 192khz don't work
I only get Sample format not available for playback: Setting of hwparams failed:
I enclosed to pastebin my alsainfo script output.
Thanks for the help !

Hello Takashi !
What should this patch do ?
The patch removes the restriction patch_nvhdmi.c sets. Instead, the driver tries to detect the supported format, rate, etc from the codec widget information.
Is it a cure for the 96, 192khz or 24bit sample playback problem ?
Possibly.
If so, will it resample or natievly pass the stream to the amplifier ?
It just enables the native support, possibly.
And, don't forget to give back the alsa-info.sh output (run with --no-upload option).
Takashi
Thank you

How about the patch below? Also, could you give alsa-info.sh output? Takashi --- diff --git a/sound/pci/hda/patch_nvhdmi.cb/sound/pci/hda/patch_nvhdmi.c
