Make sure you're using the VDPAU video renderer. Also, depending on how "latest" your drivers are, you might need the enable_msi=0 option in /etc/modprobe.d/sound.conf (see wiki page).

My ALSA drivers are from git from some days ago, and I do have enable_msi=0
However, I was not using VDPAU so I am going to test it with VDPAU enabled.

Thanks!

Unfortunately, VDPAU does not seem to be working on my laptop, at least for now (see http://www.nvnews.net/vbulletin/showthread.php?t=151135).

Is there another way of playing movies on my TV with HDMI Audio without it skipping frames?
It is not a HD movie, with only stereo audio, so it seems weird to me that it would skip frames.
Many thanks again.

Try increasing the buffer sizes.

I would think you would do better to consolidate your info in your GT230M thread.

a) you have a GT230M.. this is a GT240 thread
b) you have video skipping? this is an audio thread and has nothing to do with VDPAU

(really not trying to be a grump, only a mildly AR thread/forum dude)

larophel · 05-20-10, 10:15 AM

zim2dive: I guess you are right, I have pasted my question in my own thread now.

primerib: Care to elaborate a bit on your suggestion? I assume you mean to increase the buffer size in mplayer? There are many buffer-affecting options to mplayer. Which one do you mean? Thanks!

If you don't mind please answer in http://www.nvnews.net/vbulletin/showthread.php?t=151135

I am still having problems with my Asus GT 220. Mythdora 12.23 (Fedora 12). There's quite some confusion on my part what should be correct sound.conf for me.

Again, when doing the various speaker tests I don't get errors, but no sound. I have to umute the spdif on the hdmi every time, so I didn't forget that ever.

No sound:

@fuzzy2010: Kill the @hooks[] section of /etc/asound.conf and kill /etc/alsa/alsactl.conf completely. For good measure, kill the alias lines in /etc/modprobe.d/sound.conf too. Your probe_mask is right; enable_msi is technically not needed anymore but it doesn't hurt. (Of course, make backups of these files!)

Check the output from `lsmod | grep snd'. If snd_hda_codec_nvhdmi isn't loaded, I don't think you'd even see the device, but check anyway. If not loaded, you'll need to load it.

ok, commented out all the hook section. Moved the alsactl.conf to alsa.conf.bak. My sound.conf:

Code:

#options snd-hda-intel enable_msi=0 probe_mask=0xfff2

#alias snd-card-0 snd-hda-intel
#alias sound-slot-0 snd-hda-intel

options snd_hda_codec_nvhdmi

options snd-hda-intel enable_msi=0 probe_mask=0xffff,0xfff2
#options snd-hda-intel enable_msi=0 probe_mask=0xfff2

lsmod|grep snd_hda_codec_nvhdmi
snd_hda_codec_nvhdmi 12743 1
snd_hda_codec 83951 3 snd_hda_codec_nvhdmi,snd_hda_codec_realtek,snd_hda _intel
snd 60294 9 snd_hda_codec_nvhdmi,snd_hda_codec_realtek,snd_hda _intel,snd_hda_codec,snd_hwdep,snd_seq,snd_seq_dev ice,snd_pcm,snd_timer

unmuted in alsamixer the nvidia spdif.

Still no sound. I notice if I am watching something in MythTv and try aplay:

aplay -D plughw:1,3 Noise.wav
aplay: main:608: audio open error: Device or resource busy

Also, this produces no sound now:

aplay -D plughw:0,0 Noise.wav
Playing WAVE 'Noise.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

Pretty sure that's a syntax error, since I suspect all options targets are hyphenated, but you shouldn't need the line at all.

At any rate, the "back to basics" technique apparently hasn't gotten us anywhere (unless the presence of the line above was it, which I doubt). If you can't get it in aplay (or speaker-test), you just ain't gonna get it anywhere. There was a new reply on your original thread which you might check out; as it is Fedora-specific I can't usefully comment on it.

The only ideas I have left include doing ugly things like compiling your own ALSA and/or kernel. I can't imagine that it's down to that, but hopefully someone else will chime in.

To share my experience with a G210 (MSI N210-MD512H):
I originally had a CRT (Sony GDM-FW900) connected to the VGA connector and wanted to use a HDMI A/V receiver at the same time (Kenwood KRF-V7300D).
(I suspect) It is necessary to install the ALSA kernel modules, I successfully tested 1.0.23 (which can not be installed on older kernels, at least not 2.6.25) on 2.6.31. Without any options in /etc/modprobe.d/50-sound.conf, four Nvidia sound subdevices are detected ("7" was the working one after the other problems were solved), I added the following line:

Code:

options snd-hda-intel probe_mask=0xffff,0xfff2

It allows to only detect one Nvidia subdevice ("3"), but at the same time also detects the internal HDA Intel device.
When I connected the HDMI device for the first time, the first bad surprise was that the VGA monitor was not detected as primary device anymore (although there was no screen connected to the A/V receiver), disabling all terminals (X still ran on the CRT). Connecting the CRT via DVI solved that problem.
The next thing was that the "HDMI" symbol on my receiver was blinking sometimes (on power-up), but never indicated a connection (and I could hear no sound from MPlayer or speaker-test, but without any error messages). I had to modify my xorg.conf, adding a second screen, second monitor ("KWD KRF-V7300D") and second device (mostly identical to the existing "GeForce 210" Device0). Now the HDMI connection is up whenever X is active (but not if I switch to a terminal).
The following commands work successfully indicating 8-channel PCM, AC-3 and DTS are working as expected:

Code:

speaker-test -c8 -twav -Dplughw:1,3
speaker-test -c6 -twav -Dplughw:1,3
speaker-test -c4 -twav -Dplughw:1,3
speaker-test -c2 -twav -Dplughw:1,3
speaker-test -c1 -twav -Dplughw:1,3
mplayer file -ac hwac3 -ao alsa:device=hw=1.3
mplayer file -ac hwdts -ao alsa:device=hw=1.3

The following commands initially seem to block, and fail after a long time(-out):
(-c7 fails immediately which is probably correct behaviour)

Code:

$ speaker-test -c5 -twav -Dplughw:1,3

speaker-test 1.0.21

Note that -c5 is not so farfetched: The Neujahrskonzert is broadcast in 5.0, so the following mplayer command shows the first frame and blocks indefinitely:

Code:

mplayer Neujahrskonzert.ts -channels 6 -ao alsa:device=hw=1.3

Looking at dmesg

Code:

HDMI: detected monitor KRF-V7300D

HDMI: supports coding type MLP (Dolby TrueHD): channels = 8, rates = 48000 88200 176400 192000 384000

the remaining question is how do we get E-AC-3, TrueHD and DTS-HD output?

Your best bet is to decode them to LPCM on your computer, and send them uncompressed to your receiver. See alanwww1's guide for details. You can probably start at Post 2 since you have ALSA up and running. Hope it helps.
