Macmini 2010 sound problem over hdmi

Hi, my name is Diego im from Argentina, well i have a problem with my macmini 2010 unibody, i have set up the mini over hdmi in to my receiver ( yamaha 663 ) and hdmi out to my LCDTV, i set up in sound properties HDMI output ok all is fine but if i am listening music in itunes and turn off the tv the signal is off to receiver and the music sounds in the built in speaker of the mac mini, any idea to disable this speakers o built sound card ? i want to passtrough over hdmi with the TV off, thanks to all best regards, Diego.-

I still get daleks too from time to time if I try to use 1080i with Dolby Digital into a Sony Bravia.
The BT Vision box HDMI is known to be flaky, though it sounds like you've got an extreme example of the problem with the Tosh.
It's possible to improve things a bit by using an HDMI extender to recondition the signal before it enters the TV. It might be worth a try. Try http://www.hdcable.co.uk/

No sound over hdmi, ION2 system

Hi there
I'm trying to get sound output over hdmi connection without any success. I'm totally out of ideas as I tried it with openelec.tv and a xbmc live system. All the time I never heard anything. I tested with speaker-test and mplayer. I tried stuff from the guide here: http://breden.org.uk/2010/09/30/shuttle … ta-2-live/, http://www.nvnews.net/vbulletin/showthread.php?t=157347 and also from xbmc wiki:
-different settings of asound.conf (however afaik this does not affect speaker-test -D plughw:X,Y -cN)
-options for the snd-hda-intel module
-unmuting
-different input channels of my receiver
-different nvidia driver versions
Here are my specs:

What I noticed is that dmesg does not show any hdmi hotplug event, something like: "HDMI hot plug event: Pin=5 Presence_Detect=1 ELD_Valid=0"
So I thought maybe you arch linux people have some creative ideas what the problem is here?
PS: It can't be the hardware because it works with windows7.

No, does not work either... I need to help to figure out why the hotplugging and detecting of the receiver does not even work.

Sound works over HDMI for most of my applications(Flash, Gnome player, Skype) but I have no volume leveler under alsamixer nor does pianobar output to HDMI unless I launch it twice. The error that allows pianobar to work over HDMI is

I'm wondering, is there something I'm missing?

I am also having this problem... I get this error when I play certain songs in pianobar:

I am not sure how to fix this

[CLOSED] sound over hdmi and optical

Ok I know sound of hdmi is a pain for everyone but I've have been all over the wiki and Google and have yet to get mine working! The weird thing is... sound works in XBMC. I got movies with 5.1 sound and 2.0 sound to work as well as music and everything else (except sound effects on menu selections but i can live with them) by setting the audio device to Optical/Coax, speaker config to 5.1, enabling DD AC3 capable and setting both audio ouput device and passthrough output device both to hdmi. However it ONLY works in XBMC. I'm trying to get some emulators working and it doesn't work in them. it doesn't work in an lxde environment either or when I run:
speaker-test -c 6
If I can just get sound working over hdmi I would be happy, If I can get it to work over hdmi and the optical out both that would be even better (although I have a feeling that'll just make things harder).
Here's my soundcards listed with "cat /proc/asound/modules"

I've been all over the alsa page of the wiki. When I tried the settings under https://wiki.archlinux.org/index.php/Al … DIF_Output they were already correct.
To anyone who's bothered to read all this ( I sorry it's so long I'm just trying to be thorough) Thank you!
If anyone has any clue what I can try to fix this I would be forever grateful.
Edit: Well it looks like all that messing around I did last night trying to fix things only made it worse. Now the sound in XBMC doesn't work either.

Hi!
I spent the day asking friend google, browsing the arch wiki, ubuntu wiki and xbmc wiki.
Lastly, I made it work. I have to admit that I don't know why and don't actually understand a thing of what I did, it was trial and error. However, here is what I did:
installed alsa-oss (probably irrelevant)
set the audio output settings in xbmc to "Audio output"="Optical/Coax", "Audio output device"="Defaults" and "Passthrough output device"="hdmi".
used the following as my .asoundrc
pcm.dmixer {
type dmix
slave {
pcm "hw:0,3"
rate 44100
pcm.!default {
type hw
card 1
That's it. In case you are a sound guru willing to share your wisdom or else trying to make it work like I did, you might want some more info. Here you go.

Sound disappeared from HDMI. MSI message in dmesg.

I use a laptop with slim/xmonad and frequently plug it into my TV and found this to automate the process off setting sound and picture when i plug it in.
Tested it out and seemed to work fine, and now 2 days later, I get no sound from HDMI. PC speaker and headphones work fine and with other PC sound works over HDMI.
I checked and it does change asound.conf when I insert HDMI cable. I don't use a .asoundrc.conf for this user.
/etc/asound.conf
pcm "hw:0,3"
But I still get no sound from system or with:
speaker-test -c 2 -D plughw:0,3
I have checked alsamixer if any channels are muted and also manually restarted alsa with:
systemctl restart alsa-restore

dmesg | grep snd

I was having the same problem. Here's what worked for me:
Remove the blueray disc from the player.
Reboot the laptop.
Turn on the TV and select it's HDMI input.
Connect the HDMI cable from the TV to the laptop.
The display should transfer to the TV (laptop goes black)
Open the Mediasmart player.
Select DVD
Open "Settings" (the gear symbol)
Click "Audio" tab
Select "HDMI passthrough" and apply.
NOW, put the blueray disc into the drive.
Give it some time to start on it's own.
(Note; If you try to adjust the "settings" with a disc in the drive, or without having the HDMI cable attached, the "HDMI passthrough" will not be shown as an option.)
Now that I follow this procedure, I haven't had any further trouble. The TV plays the audio, not the laptop, and I can use my home theater sound system by taking the "audio out" from the TV and inputting it into my decoder (and turn the TV volume all the way down).
I hope this helps. I was pulling out my hair till I discovered this. Let us know if it works for you.

Sound over HDMI problems

Hi forum,
I have strange problem. I want to use a Xen HVM Domain with a ATI Card as a HTPC (got this working with a ubuntu 11.10 - want to migrate to arch). Basically everything is working with the catalyst drivers besides some sound problems. Following what is working:
with smplayer (alsa output):
- mp3, avi, mkv
vlc (with default sound - probably pulseaudio):
- mp3, avi
mkv is like stuttering and the movie gets interruped very often.
vlc (with alsa output):
- mp3, avi, mkv
mkv is like stuttering and the movie gets interruped very often.
Flash videos are showing the same behaviour - stuttering a lot.

This worked on ubuntu 11.10 but not on arch!
btw: ubuntu 12.04 does not work neither.
in default.pa i load the alsa sink module with hw:0,3 too.
behavior did not change.
any ideas, what is causing the problem? I really dont wont to switch to gentoo just to have a system without pulse (what is maybe the problem?).

Hi,
I have some news. With Kernel 3.3 and 3.2 it is not working! Using the LTS Kernel everything is fine! Any Ideas about this?

10.7.1 Audio over HDMI Problem

Hi All,
Here is a breif history of my problems with audio over HDMI. From 10.6.3 to 10.6.7 everything was working great. I have a mid 2010 i7 iMac hooked up via HDMI to a Marantz receiver which is in turn hooked up to a Panny TV. Everything worked as it should, audio went out to the receiver and video to the TV. Then the upgrade to 10.6.8 began the trouble. On the Marantz, I have a visual representation of the audio input. The unit showed that the audio was intermittently "flashing out". That was confirmed while listening to the output of the iMac via the Marantz. The image to the Panny was solid. I tried a variety of fixes (grabbing system files from 10.6.7, PRAM reset, etc.) all to no avail. So I reverted back to 10.6.7. Recently I tried again. Upgraded to 10.6.8 and applied the supplimental update that was supposed to fix the audio over HDMI issue. No good there either. I got the same audio dropping out problem. So I figured I'd go all out and try to upgrade to Lion. The upgrade went smoothly but the problem has morphed a bit. Now when the Marantz is on the iMac input, the iMac doesn't output audio or video ver HDMI. The moment I switch to another input on the Marantz (DVD for example) the iMac senses a switch and outputs audio and video. (At least that is what Display and Sound preferences indicate, as I'm not on the correct input on the receiver, I have no way to verify that anything is actually happening). So I'm back to square one. Do I downgrade back to 10.6.7? Any opinions or similar experiences out there? TIA!!

If anyone's curious, I seemed to have solved the problem the other night. I simply switched the HDMI input on the receiver. Previously it was going into the "game" HDMI input, and I switched it to the "DVD" HDMI input. I'm not really sure why that made a difference. As I mentioned before, all was fine under 10.6.7. Perhaps under 10.6.8 and later, Apple changed the HDCP and the Marantz can only make sense out of it on a "traditional video input" (ie DVD). That's the only explanation I can come up with. Oh well, all's well that end's well I guess.

UPDATE 1: After a good night's sleep, and after doing a bit more reading on alsa-project.org (big props to this page), I managed to get a much better ~/.asoundrc together. It solves all my problems, and I can do everything I need. I've preserved the post below in case anyone else runs into these issues, and I'll post my solution as a response to this post.
UPDATE 2: Looks like I celebrated too early. Got more strange problems. Screw it, I'm going back to PulseAudio. I just wrote a wrapper script to kill and restart Pulse for applications that really, really need ALSA.
Okay. I've almost completely worn out my fingers trying to get this working. I feel like I'm playing Whack-a-Mole. This is a bit of a lengthy post, but I'll try my best to describe every problem I've encountered in as much detail as I can, followed by the solutions I found, followed by the problems each solution brought with it. By going through everything this way, mole by mole, hopefully it'll be easy to follow along and help me come to a universally working solution.
Summarized Version of Problems:
5.1 surround works only on specific applications which are robust enough to allow me to manually specify audio output options, and only if ALSA isn't configured at all
once I've configured ALSA, sound works on every application, but it's all downmixed to 2.0 stereo from this point on
installing PulseAudio lets me choose 5.1 surround as a default, but brings with it its own problems and drawbacks, namely the lack of passthrough support for encoded streams
Long-Winded Version:
I have my computer connected over HDMI to an AVR with a 5.1 surround speaker system. At first, I didn't have anything configured in ~/.asoundrc (or its global equivalent, /etc/asound.conf). Neither file existed, so everything was running off defaults. I got the name and device number of my card from aplay, ran speaker-test and played a six-channel test file in mplayer.

Everything seemed well, all six channels played from the correct location on both tests, but I did realize that the device number of the card was 3, not 0. A lot of applications that aren't as configurable expect the default card/device to be set properly, and audio won't work in those applications without specifying that in ALSA's configuration. Knowing this, I set the following in my ~/.asoundrc:
pcm.!default {
type hw
card HDMI
device 3
ctl.!default {
type hw
card HDMI
device 3
This, however, ended up causing more problems. Oh, it made sound work on everything by default after that, but only for one application at a time! That surpised me, as I thought ALSA's big advantage over OSS is that it can multitask. Running the speaker-test the way I did earlier turned out fine, but when I tried playing that test file in mplayer, things got weird again. Here's the output from mplayer:

Why the hell is it looking for pcmC0D0p? It should be looking at pcmC0D3p. Did it not get the memo from ~/.asoundrc? Urgh.
I've also tried '-af channels=6' in place of '-channels 6' but the same result happened. It does the same thing without the '-ao alsa' option, I just specified it to trim down the output, so that I wouldn't be copying and pasting all kinds of other errors about not finding OSS or JACK or other things I don't have installed.
If I symlink /dev/snd/pcmC0D0p to /dev/snd/pcmC0D3p, it'll fix the problem, but that feels like one ugly kludge. I'd have to do it again over and over every time I reboot, too.
Not sure if this would help matters or not, but if anyone knows how to change my card's device number from 3 to 0, I'd like to try that as well, but I'm not sure how to do that sort of thing. I'm just guessing it might be worth trying, since everything looks for card0/device0 by default, and that kludge I tried earlier did have an effect, so maybe if we can just switch those device numbers with each other, everything would work smoothly without having to force anything through ALSA's configuration at all. I believe card0/device0 belongs to the Host Bridge... is there a way to have them trade their device numbers for one another's in a safe manner?
I can also get it to play if I specify the device like I did in my first test, using '-ao alsa:device=hdmi', but that defeats the purpose of getting good defaults set if I still have to set everything by hand before I play something. If I try playing the test file without any options, like so:
$ mplayer Nums_5dot1_24_48000.wav
... it will play, but only in two-channel stereo, and the parts that should happen in the center, rear and LFE channels get downmixed into the left and right channels.
I can get it to work in aplay, though! All six channels! Not that I plan on using this as my primary multimedia software.
$ aplay -c6 Nums_5dot1_24_48000.wav
The only solution I found so far that allows me to have 5.1 audio by default is to install the PulseAudio server, which is able to find a sink/source named 'alsa_output.pci-0000_00_03.0.hdmi-surround' and lets me choose that as my default. Only problem with this is that PulseAudio has its own problems.
Aside from the crackling sound issues in some Wine games, Pulse also has a much bigger drawback -- a complete lack of passthrough support, meaning I can't use encoded streams such as Dolby DTS and TrueHD with PulseAudio. I have a Harman/Kardon AVR and I'd like to get my money's worth out of it, so I'd really like to figure out a solution in ALSA without using Pulse at all.
Does anyone know how I can have my cake and eat it, too? I just need 5.1 surround, by default, in ALSA without PulseAudio.
HUGE thanks to anyone who tries to help here. This is really making me sad and frustrated, I've been using Arch for quite a while now and this is the first real big stumper I've come across that forced me to post a thread. Otherwise I've been having a wonderful time.
Edited because I tried something different that removed *some* issues, but the above problems still remain.

Well, I thought I fixed it doing this...
pcm.!default {
type plug
slave.pcm "dmixer"
pcm.dmixer {
type dmix
ipc_key 1138
ipc_key_add_uid true
slave {
pcm "hw:0,3"
format S32_LE
channels 8
rate 192000
period_size 9600
buffer_size 38400
... but then realized it strangely makes applications that run at 640x480 have no sound at all. No idea why the video resolution is screwing up the sound, but that's what's happening, because if I set the resolution any higher, the sound comes back.
I'm going back to PulseAudio, I feel like ALSA is mocking me. I wrote a wrapper script for the few times where pure, Pulse-less ALSA will be necessary for me. Here it is, in case it helps anyone else. I've tested it with XBMC, it turns off Pulse and allows ALSA to pass through encoded streams unhindered. It also works with some Wine applications that have scratchy audio glitches in Pulse.
#!/bin/bash
echo "autospawn = no" > $HOME/.config/pulse/client.conf
pulseaudio --kill &> /dev/null
"$*"
rm -f $HOME/.config/pulse/client.conf
pulseaudio --start &> /dev/null
I'm removing the SOLVED tag because technically I didn't resolve any of my original issues, I more or less gave up on what I wanted to do and found another way to satisfy my needs, but it still isn't as elegant as I had hoped for. In any case, I'm done with this issue for now and the forseeable near-future, but if anyone has anything further to add, feel free.

Qosmio G50 No sound over HDMI

*Qosmio G50 No sound over HDMI*
Hi all,
Hopefully anyone recognises the following and would be so kind to help me. I have searched the forum and tried severall of the offered solutions mainly applicable to Vista, but still.
I hooked up my Qosmio G50 to my Philips LCD by HDMI cable. Picture is ok but there is no sound. I tested the cable with a Toshiba Satelite Pro L550 and it works allright. Picture and Sound are working. But that laptop has Intel HDMI audio.
I'm running Windows 7 Home Premium 64 bit. I upgraded by Toshiba update DVD from Vista 64 bit. Sadly I do not know for sure if HDMI audio did work before that. I think so because I did use the laptop for watching a movie on a Panasonic plasma. But I can not remember if that was before or after the upgrade.
Realtek HD Audio device is installed driver version 6.0.1.5923
Realtek HDMI Output is selected als default playback device.
Testing gives me graphical response ( the indicator flashes ) but no audible sound from my tv.
Choosing the other audio device Realtek Digital output changes nothing and I do not believe that this would work anyway.
I have tried removing the device and reinstalling the original drivers. I have tried REaltek drivers from their website.
I have tried changing the view to HDMI only but that does nog change anything either.
One thing that worries me is that under Sound / Realtek HDMI Output / properties / Supported Formats there are no formats present. The Satelite gives me DTS audio and some other. So I am wondering if there should be formats present and if so how can I change this / add any.
Please forgive me if there are errors in the text. I am translating this from a dutch language version of Windows 7.
Please help me. Any suggestions are welcome!

Jeka-?? & PinkPanther thanks for your replies!
The solution for the G30 you mention is not the one for me I am sorry to say. I have tried that one allready. Windows automatically switches on the HDMI audio out when I connect an HDMI cable. Connecting the cable before switching on the TV and laptop is a good thing to try because it eliminates possible problems with the connection. The connection in my case is ok.
At some point I concluded that there must be a softwareproblem of some sort.
I have found the solution over night. Could not sleep anyway. I did not know that the videodrivers are also handling HDMI audio out but in a way it makes sense. I have completely deinstalled the NVIDIA video drivers. After downloading the latest drivers and installing them everything works absolutely fine!

Problems with FLAC 5.1 audio over HDMI and mpv

The last mpv update (0.7) seems to have changed the way it gets info about the audio playback device.
Last week, I could play videos with FLAC 5.1 audio over HDMI without any problem. My .asoundrc was just:
pcm.!default {
type hw
card 0
device 3
But after the last update, if I try to play a video while the default pcm device is set to HDMI, I get this error:
mpv: ../audio/chmap_sel.c:89: mp_chmap_sel_add_map: Assertion `s->num_chmaps < (sizeof(s->chmaps) / sizeof((s->chmaps)[0]))' failed.
Aborted (core dumped)
I tried downmixing, since the problem seems the number of channels.
I added this to my .asoundrc:
pcm.!surround51 {
type vdownmix
slave.pcm "default"
pcm.!surround40 {
type vdownmix
slave.pcm "default" {
Now mpv starts without errors but I hear no sound.
Everything is fine in mplayer, even without the downmixing in .asoundrc
What should I add to my .asoundrc so that mpv recognises the playback device correctly?

So this is merely a mpv problem.
Good to know, I'll just wait for the update

Upgraded Qosmio X500-10T to Win 8.1: Sound drivers for 5.1 over HDMI

Hello *brilliant* Toshiba community,
I have recently upgraded my Qosmio X500-10T from 64-bit Windows 7 to 64-bit Windows 8.1.
I have left Windows to download driver updates.
My setup: Qosmio (HDMI) => Yamaha AV receiver (HDMI) => Samsun LCD TV.
_The Problem:_ Playing a video file (in MPC-HC) with 5.1 sound only outputs 2 channel PCM.
Would it be better to install the Win 7 drivers from Toshiba even though they are older and for a different OS, or install windows 8.1 drivers from another Qosmio, or leave the Win 8.1 drivers found by Microsoft?
This driver issue is made more problematic as I don't actually know what the technical hardware components are in the machine so its not as though I can find a win 8 driver for them.
As always any help or suggestions are greatly appreciated.
Buzz

Hi
From my knowledge the Win 7 drivers are totally different from Win 8.1 drivers and I doubt that Win 7 driver would work properly on Windows 8.1 system. However, you can test such Win 7 drivers too. But of course I would recommend you to use the Win 8.1 drivers released for other notebook series.
As Im not mistaken the Qosmio X500 needs 2 sound drivers: Conexant (chip CX20583-10Z) sound driver as well as the nVidia sound driver (for HDMI)

Qosmio X70-A-12N - no sound over HDMI after Win 8.1 installation

Hallo,
I installed on my Qosmio Windows 8.1 and all driver.
Now I have a Problem with HDMI Sound.
When I connect with TV, I see the Picture on TV but don't get sound.
I go to Control Panel: Sounds and Multimedi and I see the internal devices (loudspeaker from Laptop and Headset).
I activated to see disconnected devices and no other devices will be displayed.
I assume, it fail a driver.
I installed Sound driver, DTS Studio Sound, Toshiba Audio Enhancement and SRS Premium Sound HD Plug-In.
I don't installed the regestry patch -> For what I need it?
Have you an idea to solve my problem?
THX
Richard
(Sorry for my bad english)

Hi
>I installed on my Qosmio Windows 8.1 and all driver.
As far as I know the Qosmio X70-A-12N were preinstalled with Windows 8.1 64bit system and this OS was configured by Toshiba.
Did you install new Windows 8.1 or did you use the Toshiba system?
Did you create recovery medium (recovery disk or USB flash memory stick)?
In case you create such recovery disk, I would recommend you to use it in order to set the system back to factory settings. This should fix your HDMI sound issue.
How about other Toshiba software installation like for example Toshiba system driver, display driver etc? Did you install all the Win 8.1 drivers and tools which were released for this unit?
Missing software could be main reason for your HDMI issue

Sound over HDMI works, but laptop sound isn't working after...

Hey,
First, sound over HDMI was not working on my laptop, but when I followed this section of Alsa Wiki it worked.
So I created the ~/.asoundrc file containing:
pcm.!default {
type hw
card 0
device 3
But now, when I unplug my HDMI cable, and want to listen to music using my laptop built-in speakers/jack speakers, it doesn't work anymore, even if I restart Alsa.
In fact, I need to delete the .asoundrc file AND restart Alsa in order to get it work.
Is there a way to make both sound over HDMI, and built-in speakers works automatically depending on if my laptop is/is not connected to my TV ?
Thanks

You need to restore the card and/or device number to those for your laptop speakers, as determined by:
aplay -l
To do this automatically, you will need to use scripts called by udev, as described a little further down.
