Hi Fengguang, I ran the command as requested:

$ speaker-test -Dhw:0,3 -c8 -twav

speaker-test 1.0.21

Playback device is hw:0,3 Stream parameters are 48000Hz, S16_LE, 8 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 16 to 4096 Period size range from 8 to 2048 Using max buffer size 4096 Periods = 4 was set period_size = 1024 was set buffer_size = 4096 0 - Front Left 4 - Center 1 - Front Right 7 - Side Right 3 - Rear Right 2 - Rear Left 6 - Side Left 5 - LFE Time per period = 11.306881

Unfortunately there was no audio output. :(

Thanks Steve

Hi cdstealer,

It looks all sane with HDMI audio. Would you verify HDMI playback with command

    speaker-test -Dhw:0,3 -c8 -twav

?

Or are there any more concerns?

Thanks, Fengguang

Hi Fengguang, I've got HDMI sound working. This is what I did:

Glad to hear that :)

Steps to recreate:

Stopped alsasound (from portage) removed from alsasound from rc-update downloaded Realteks HD drivers from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&... http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false unpacked the archive and ran the install script (as root) replaced the /etc/conf/alsasound with the /etc/conf/aslasound.new rebooted as modules could not be reloaded.

This is the realtek-linux-audiopack-5.14. So it looks like the Intel side of things are solid, it was the Realtek drivers that were the problem. Thank you very much for you help and time. Hopefully the correct drivers will make it into the kernel soon.

I'm a little puzzled though. HDMI audio should be independent on Realtek HD audio. And it's normally OK to just use the in-kernel Realtek HD audio driver.

Thanks, Fengguang
