Sound issues still...

I'm going to finally try and tackle the sound issue with my box currently he
volume is way to low.

I ran 'aplay -L' and this was the result:

*front:CARD=NVidia,DEV=0
HDA NVidia, ALC888 Analog
Front speakers
surround40:CARD=NVidia,DEV=0
HDA NVidia, ALC888 Analog
4.0 Surround output to Front and Rear speakers
surround41:CARD=NVidia,DEV=0
HDA NVidia, ALC888 Analog
4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=NVidia,DEV=0
HDA NVidia, ALC888 Analog
5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=NVidia,DEV=0
HDA NVidia, ALC888 Analog
5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=NVidia,DEV=0
HDA NVidia, ALC888 Analog
7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
hdmi:CARD=NVidia,DEV=0
HDA NVidia
HDMI Audio Output
null*

The board I'm using is an Zotac 8300 with HDMI, originally I wasn't able to
get the HDMI sound working but was curious if anyone had any successes with
this board or had some suggestions.

The board from what I can see does audio over HDMI and my TV is a Sammy
LNT4665 and I think it shouldn't have any problems with audio over HDMI but
I was only able to get Analog sound going.

Also, does Myth now support PulseAudio?

Thanks for any advice or suggestions.

A JM,

I have HDMI sound working for Live TV, Recorded TV, and DVD playback
now. My box is the ASRock 330 ION which should be similar to the Zotac
8300 from what I can see.

For live tv viewing I had to enable the option Settings -> TV Settings
-> Playback -> General Playback -> Extra audio buffering. If I didn't
I would see "WriteAudio: buffer underrun" logged with sound breakups
when watching Live TV. The other Settings -> General -> Sound config I
used was:

Audio output device: ALSA:default
Passthrough output device: Default
Max Audio Channels: Stereo
Upmix: Passive
AC3 audio upmixer - unchecked
Enable AC3 to SPDIF passthrough - unchecked
Enable DTS to SPDIF passthrough - unchecked
Agressive Sound card Buffering - unchecked
Use internal volume controls - unchecked

And my /etc/asound.conf looks like this:

pcm.!default {
type plug
slave.pcm "hdmi"
}

I'm running JYA's stable 0.21-fixes with Ubuntu 9.04 at the moment.

If you're using my repo, you would only get stereo sound then, not 5.1

If you want surround sound you have to set the max audio channels to 5.1

Scott, thanks for the reply.

What OS are you running, I'm running Ubuntu and by default it has PulseAudio
running do you know if that needs to be uninstalled or can I just try and
get Alsa running as the default sound system?

Thanks,

if running 0.22, then yes, you should disable or uninstall the
pulseaudio server.

Seeing this in the syslog not sure why I would be lacking priveleges?

Jean-Yves, is there some updated directions around that I could follow for
setting up ALSA and HDMI sound?
