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

Simultaneous audio over HDMI and line out optical

Anyone know if this is possible on the new mini?
I currently use an AppleTV with HDMI to TV and optical digital to my older surround processor which does not accept HDMI.
AppleTV is useful in that it outputs audio simultaneously over all audio connections - I suspect new Mac Mini might only allow single audio output at a time.

Correct. You choose your audio output in the sound control panel (or Option-click on the sound icon in toolbar).
That's ideal then really.
...- that would then allow HDMI video to TV, toslink to AV processor, and analogue audio from AV processor to TV analogue audio in to use when you only need the audio via TV speakers...
I doubt the TV will take an analog audio in at the same time as HDMI video in. It likely only accepts analog audio on inputs that are also analog for video (component, s-video, composite).
You're right, unlilely to be configurable for HDMI, there might be the odd set that allowed something like this but in general most wouldn't.
...A small utility/script might be feasible to toggle between the two on the Mini...
Yes, entirely possible.
Another option would be to do what I do: Disable the TV speakers and use the receiver for all sound. Since TV speakers suck, this is a great option. I haven't used built-in TV speakers for at least 15 years.
I generally do that too, just sometimes for late night listening when others are in bed I switch to the TV speakers, but actually it'd be far easier with no TV audio as you'd not run into those instances when both TV and hi-fi are outputting and messing up the audio effect entirely.

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.
Thanks.

No audio over HDMI

So, I generally use Windows via Bootcamp on my 2012 Macbook Pro (15"), and I frequently hook it up to my projector and media center via an HDMI cable. Everything was working perfectly up until three days ago, when suddenly the laptop wouldn't send audio over HDMI. On the Windows side, I spent a couple days doing everything the internet said I should try (reinstalling drivers, rolling back drivers and updates, managine audio output devices, etc.) and never got anything. My graphics driver could see the HDMI device and said that there should be an HDMI device on my sound control, but it never showed up.
I figured it was a problem with Windows, so I jumped over to the Mac side, where I'm running Mavericks. Just like the Windows side, video works flawlessly but there's no audio output. In Preferences, under "Sound" and "Output", I only see the speakers of my laptop and one AirPlay-compatible device that's set up in the room. Headphones work great. But there's no way to send audio over HDMI.
Just to be safe, I installed a fresh version of Windows and a fresh version of Mavericks, and I'm still not getting anything. Is there something that I'm missing? Because right now it feels like it's a hardware issue, but there's no reason that it should be. And I'm confused about why I still have perfect HDMI video if it is a hardware issue.
Any help on the issue would be greatly appreciated. Thanks!

I should mention, by the way, that I ruled out issues with my HDMI cable or other hardware. I have tried multiple cables with the same results, and my roommates can all send audio over HDMI without problems.

Ok, rc7 is out. Dave Airlie disabled HDMI Audio on rv710,rv730.
Dave Airlie (9):
drm/radeon/kms: fix incorrect logic in DP vs eDP connector checking.
drm/radeon/kms: use active device to pick connector for encoder
drm/kms/radeon: pick digitial encoders smarter. (v3)
drm/radeon/kms: release agp on error.
drm/radeon/kms: move radeon KMS on/off switch out of staging.
drm/radeon/kms: disable HDMI audio for now on rv710/rv730
drm/radeon/kms: make initial state of load detect property correct.
drm/radeon/kms: rs400/480 MC setup is different than r300.
drm/radeon/kms: fix r300 vram width calculations
EDIT: Further more, Jerome Glisse talked about future radeon development [1]
Coming up in the Radeon DRM for the Linux 2.6.34 kernel (or releases thereafter) is support for un-mappable VRAM, support for Evergreen GPUs (Radeon HD 5000 "R800" series), use of the Linux power management API for better suspend-and-resume support, better DRM power management, HDMI audio for R700/800 graphics processors, and improved GPU lock-up recording.
Therefore, Audio over HDMI is expected for 2.6.34+!

Pavilion 2150XX: Does it Have to Transmit Audio over HDMI?

Hi,
I have the Pavilion dv6 2150er, and I have the "No sound over HDMI" issue described here in numerous threads.
The problem is the issue won't go away after trying everything: different HDMI ports on TV, different cables, re-installing drivers, deleting all relevant devices from Device Manager and re-installing the drivers (Intel chipset, NVIDIA Forceware, IDT Audio), booting with the cable already connected etc...
The last thing I have tried is uninstalling the latest Forceware version taken from the NVIDIA site, running Driver Sweeper, re-booting, and installing the latest available on the HP site dated 2010. With this driver, I get a BSOD immediately after plugging in the cable or during the bootup process, if the cable is plugged in.
Now I'm really lost...
So, the question is: does the video card (NVIDIA GeForce 230M) installed on 2150XX notebooks have the necessary audio hardware to transmit sound over HDMI?
PS: I do have the NVIDIA HDMI Codec (or maybe it's called NVIDIA HD Audio Codec, can't remember now) listed four times in Device Manager, but it doesn't appear among other sound devices in Control Panel. All I have is Speakers, Microphones, and SPDIF. Setting SPDIF as default doesn't work either.
PPS: I am running Windows 7 x64 Ultimate.
Thanks in advance.

Just FYI:
I've solved the issue by simply unplugging the TV from the power supply. Simply switching it off with the remote control or with a hardware button didn't work.
Now I can transmit sound over HDMI, and this also fixed the problem with the sound coming from my Apacer multimedia player.
Please take note of this trick

[SOLVED] Audio over HDMI stopped working? (Intel/i915)

My audio over HDMI was working fine until recently and I can't figure out what's stopped it from working... My configs haven't changed and aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav gives no errors, but no sound can be heard. There are no errors/messages in dmesg either.
My graphics card uses the Intel i915 chipset (Asus laptop).
Config stuff:
/etc/asound.conf:
pcm.!default {
type hw
card 0
device 3
ctl.!default {
type hw
card 0
device 3
aplay -l:

Yeah I checked and everything is fine... this is really weird!
I've tested audio over HDMI on windows, so I know it's not the cable/HDMI port. I've looked through my pacman.log (I tend to update daily) and the only thing I can see which could affect it is a kernel update and intel-dri. I tried downgrading those and re-tested, to no avail.
I also installed pulseaudio and pulseaudio-alsa before it stopped working. This could have broken it, but I've since uninstalled them and replaced /etc/asound.conf with my original, so that rules those out; unless there is something else that pulse could have broken?
Cheers

785GT-E63 - Audio over HDMI

Hello All,
I couldn't find this info anywhere, and am hoping that folks here can assist me.
Does this board support audio over HDMI?
I would like to use this board in HTPC setup.
Thank You!!!

Quote from: Fredrik on 20-April-10, 05:16:50
Hello!
Speaking of info. - Please describe your system in some detail, and do not forget to mention the specs of your PSU. There is a sticker on the PSU box.
Generally HDMI transports sound, yes.
Thanks for the reply.
My set-up is pretty simple.
Besides the new MB and CPU (which i got at a great deal on $115 for both) all the components are being recycled from other PCs.
MSI - 785GT-E63
Athlon II 630
2x512MB of DDR2 Ram
Thermaltake TR2 430W PSU
nMEDIAPC HTPC Case 6000B
Windows 7 Ultimate
1.5TB Segate HDD
2TB Hitachi HDD
Video capture card (don't know the specs)
I do not have a dedicated video card, and for my purposes i don't think i need one.
I would like this HTPC to output audio to a 5.1 channel system powered by Onkyo TX-SR507 Receiver through HDMI
This will be used to watch 720/1080p video downloads, brows pictures, basic online browsing and maybe convert some of my old family VHS videos.

P7NGM-digital : audio over HDMI ?

Hello,
I read elsewhere that for this board, P7NGM-digital, audio over HDMI was not possible ?
Is it true ?
As it is not working for me.

Problem solved. Uninstalled all windows updates and display drivers. Reinstalled windows updates in groups of no more than 5 at a time, restarting after each group. Installed latest Intel display driver, restarted. Works like a charm now.

I can't start Facetime. Keep getting a pop-up window saying that "an internal FaceTime error occured. There was a problem with FaceTime. You need to quit and open FaceTime again". I keep retrying to open and keep getting the same message over again.

Problems with SB X-fi Audio, fast help requi

Hey!
i've got an BIG problem with my Soundblaster X-Fi Audio.
I can hear any sound that is played on the computer, so there is no problem there, i have installed it correctly and deactivated my on-board soundcard.
But sometimes, either when i'm producing music, or mixing music in diffenrent programs, the sound just "hangs up" and everytime i'm trying to play something after it freezes, even on itunes, the music wont even start. Its not even beginning to play, the marker in the field
that shows how far in the track "you are" is not moving.
This is very annoying, and i have to reboot my computer to solve the thing everytime.
I dont have any other problems with the soundcard, the drivers is updated and so on.

oh , i forgot
my computer runs windows Xp proffesional

Z68MA-ED55 (B3) - Realtek HD Audio over HDMI

Does anyone know if the motherboard Z68MA-ED55 (B3) is able to get HD Audio out from the HDMI connection?
When I installed the Realtek HD codec I only see listed two digital outs: optical and atapi. (which I don't know what atapi is for)
I think my motherboard need bios updates as mine is in version A1, and the latest A4 seems to fix some audio tables (which I don't know what it means neither..
Anyone has HD audio over HDMI for this board or advice about what to try?
thanks
Update:
Seems my board should support HDMI HD Audio out..
From MSI board document:
Chip integrated by Realtek® ALC892
Download the manual at: http://www.msi.com/product/mb/Z68MA-ED55--B3-.html#?div=Manual
From Realtek ALC892:
The ALC892 also features secondary SPDIF-OUT output and converter to transport digital audio output to a High Definition Media Interface (HDMI) transmitter.

Any luck getting HD audio to work over HDMI?

Hi there
Sorry for hijacking your thread as put by Dahveed. However I have resolved my issue so I thought I'll share it with the rest of you.
I checked for the error 3194 in youtube and I found some good videos that tell you how to resolve the problem. The issue I was facing was the actually (I know because I have resolved it now) the communication between my computer and apple server which can be fixed as following (if you are using windows):
There is file in following directory:
C:\Windows/system32/drivers/etc/hosts
The file normally has no extension and it is in file format. You need to open it and make sure that every line that has apple server id starts with "#". In my case one of the line started directly with the ip address and then gs.apple.com.
Perform your restore/update after that and hopefully it should be resolved (mine did).
Cheers

I have problems with outgoing call no audio, only works with speaker. I bought my iphone on december 2011.

I have problems with outgoing call no audio, only works with speaker. I bought my iphone on december 2011.

Had the same problem, no audio on incoming or outgoing calls and only could hear the conversation of the call if I put on speaker. It seemed to start after I did a recent IOS update this past month. I tried restart, reset and restore of my iPhone but nothing changed. It appears not to be a software issue but a hardware problem. I got my phone this past summer so it was still under warranty and got it replaced.
