5.1 Audio Using S/PDIF And GStreamer

These both work:
VLC -> ALSA S/PDIF Optical Out -> Surround Receiver = perfect 5.1 sound
MPlayer -> ALSA S/PDIF Optical Out -> Surround Receiver = perfect 5.1 sound
This fails:
Totem -> ALSA* -> Surround Receiver = anything but 5.1 sound
* i've tried just about every .asoundrc, /etc/asound.conf, gstreamer-properties option on the planet. I can always get sound, but Totem always down-samples the stream to something less than 5.1; some options give 2.1, some map the rear channels to front, etc. Yes, I've tried AC-passthu in totem settings (tried them all). I've tried specifying digital out within gstreamer-properties. I've tried every trick I could find for alsa... but it's not an alsa problem as both vlc and mplayer get it right without any .asoundrc or /etc/asound.conf.
I HAVE been able to play clips manually (via gst-launch) and achieve perfect digital sound on all 5.1 channels, but NEVER from within totem. So I guess I'm asking if anyone has gotten totem to pass 5.1 channel digital audio out to a receiver and actually had all 5.1 channels work?
Note: I'm already certain this is trivial with non-s/pdif outputs... I'm interested in s/pdif only.
I've spoken to some gstreamer developers and they say that gstreamer is most certainly capable of doing what I ask; it is just up to the players (like totem) to get it right. Anyone know of a gstreamer-based video app that gets it right? I've been assured that Fluendo's Moovida works, but I'd like to find another (free) way.
Thanks

Please don't forget to post the solution if you found one yourself, to help people who might run into the same issue as asked to in [1],[2].

How do I record audio using Virus TI and Apogee Duet? What is the best set up?

I am running Logic 9 with Virus TI Snow and an Apogee Duet. I have been using the Virus sound card to bounce virus sounds to audio on logic 9 but want to record the audio through the apogee sound card. How do I do this? I have tried but cant seem to monitor the sound. What is the best setup?
Also does anyone know if it will make much difference in sound quality using the Apogee sound card as opposed to the Virus?

Hi,
I'm doing this from memory, as I'm not in front of my Mac right now.. but... The Apogee installer should have installed an "apogee" control panel app on your computer. [maybe re-install?].
In Logic's Menu, go to > Options> Open Apogee Control Panel, to open it [if it's properly installed...]
When you launch that app, it has an option on one of the screens to "monitor" your inputs and adjust levels in and out of logic and, bypass the latency that causes a recording delay when doing live vocals, etc.. You can find that how to do that if you get stuck, via goggle or on the Apogee site.
As far as which sound card option is better [Virus or Apogee] DEFINITELY Apogee. Apogee is "studio standard" for high quality sound in major digital studios world wide. I'm not saying the virus is bad, but Apogee is amazing.
I went back to my old recordings and mixes I did without the Apogee and was shocked at what I did NOT hear !
Definitely Apogee !
I have a Virus TI. When you run it as a plug-in in Logic, I believe you should be able to select and simply "render the track as audio" or "mix the solo track to disc and re-import it, directly bypassing any interface by going directly to disc [via the usb cable] for the highest quality sound. Again probably Google, YouTube [tutorial videos] or the Virus site has info or downloadable manuals or Logic tutorials..
Hope this helps !

Dual monitor use audio output for movie and other for MBP

is it possible im watching a movie on one and wated to answer factime call or watch youtube on my mbp and just screamed out my tv speakers.....i want fual monitoring but separate audio any help?

Other alternatives include
I know on mackbooks I've seen firewire used as an input for a Weiss Dac if you're into two channel audio. Do any reiceivers take firewire as an input for hometheater? Has anyone tested Firewire outputs on their W series? I'm told that firewire is sometimes preferable to USB, I'm not sure why this would be, can USB support passthrough of DTS encoded signals?
In the case that firewire works and you Do not have a firewire source, maybe something like this would be of value It converts firewire to digital coaxial s/pdif and allows passthrough of DTS and AC3.
http://www.m-audio.com/images/global/manuals/FireWire-Audiophile_Manual.pdf
As I'm into audio the critical thing here (and what you're paying for when you purchase blue-ray, is maintaining the digital information from the disk in an unconverted form. You want a direct bit pass through, and you want as little jitter introduced to the signal as possible. You most certainly don't want the sound card getting in the way, Digtital to Analog converting and then reverse packaging it up and putting it out over the soundcard digital out. My problem is I'm not familiar enough with computer audio to know how exactly the sounds is transmitted from your blue ray drive to the digital interface you've chosen.
Anyone know why USB digital out would not be a prefered method?

How do I use one audio jack as input and one as output?

On my MacBook Pro, if I get a USB-headphone connector (to add another audio port), will I be able to set one audio port as input and the other as output? To use the port coming out of the USB jack as a headphone jack, and plug a mic/output device into the computer's port?
I'm thinking about buying a "Sabrent USB External Stereo Sound Adapter". I have a preamp that is NOT an interface, and I want to be able to monitor what I'm doing so I can multitrack. But my MacBook only having one audio 1/8 inch jack makes it so I have to choose either input OR output...I'm hoping if I add an extra port via USB I'll be able to have one of each.
Thank you!

Yes, either way round. In System Preferences>Sound you can set the input and output ports separately.
Roger, the System setting have -Nothing- to do with the question being asked. Do you use Logic Pro audio software? If you did you would know Logic has it's own audio settings that run independently from the System audio. There's also the fact that Maverick has problems with "some" older USB 2.0 audio hardware. Basically, this is not a slam-dunk, that's why I suggested asking someone if they've used this combination before. Although... the USB audio device is cheap ($10) it might be worth it to try. Still.............**
** I question the wisdom of using cheap audio hardware on a computer that cost $1000+, software that costs $200 and then using the internal audio chip ($2) and an external monitoring device that costs $10. Defeats the whole purpose of using professional audio software.

Eric,
Thanks for your reply. Realtek audio works only in playback. There is a stereo mix in the mixer but the recording controls are not operable with no sliders in the mixer for any recording option. Slider controls appear to be grayed out. Can't figure out how to enable them. Downloaded newest drivers to no avail.
The M Audio control panel has no apparent option for recording stereo mix. Adobe ignores the sound from the DVD or CD and shows flatline.
I'm trying to record the sound from the DVD not rip the track.
When I go to Audio Driver Setup and select Audition 3.0 windows sound, there is no input device installed.
I'm thinking of going back to a decent internal Soundblaster card like I have on my 8 year old machine I am replacing.

I am considering purchasing the Mac mini for home studio audio production using Adobe Audition and a USB microphone. Will the base mini model run these programs?

I am considering purchasing the Mac mini for home studio audio production using Adobe Audition and a USB microphone. Will the base mini model run these programs?

The base mini has 4GB and a 5400 RPM hard drive. It is slow to start up and slow to launch large application such as Word (and I'd assume Adobe Audition) due to the slow drive. I've not used a new 4GB model, just the 8GB model, and the 8GB model (except for the slow drive) handles everything I've thrown at it, including running Photoshop, Word, Safari, and Mail at the same time but there is sometimes a delay switching between programs as the swapfile is updated. Overall I was not happy with the 5400 RPM drive (perhaps because I have MBA and iMac with Fusion drive) so I eventually upgraded it with an SSD. Now the mini is truly a warrior.

I am using elements 10 and only getting audio not video. Can anyone please explain why? I am a total newbie to video.

Just saw your thread, and it looked like a candidate for the Premiere Elements 10 NVIDIA GeForce Roll Back the Driver issue. If your computer uses a NVIDIA GeForce video card/graphics card, then the following applies to you. You do not want to update the driver. Rather you want to roll back the driver version, probably to about May 2013. For your convenience I have done a copy/paste of the forum announcement which gives all the details and fix of the matter.
Premiere Elements 10 NVIDIA Video Card Driver Roll Back
If you are a Premiere Elements 10 user whose Windows computer uses a NVIDIA GeForce video card and you are experiencing Premiere Elements 10 display and/or unexplained program behavior, then your first line of troubleshooting needs to be rolling back the video card driver version instead of assuring that it is up to date.
Since October 2013 to the present, there have been a growing number of reports about display and unexplained workflow glitches specific to the Premiere Elements 10 user whose Windows computer has a NVIDIA GeForce video card. If this applies to you, then the “user to user” remedy is to roll back the NVIDIA GeForce video card driver as far as is necessary to get rid of the problems. The typical driver roll back has gone back as far as March – July 2013 in order to get a working Premiere Elements 10. Neither NVIDIA nor Adobe has taken any corrective action in this regard to date, and none is expected moving forward.
Since October 2013, the following thread has tried to keep up with the Premiere Elements 10 NVIDIA reports
http://forums.adobe.com/thread/1317675
Older NVIDIA GeForce drivers can be found

http://atr935.blogspot.com/2014/02/pe10-nvidia-video-card-roll-back.html
This matter has been very specific to the Premiere Elements 10 NVIDIA GeForce card user. So, if your computer is using other than a NVIDIA GeForce card, it is likely that the message does not apply to you, and we can then explore other troubleshooting possibities.
Looking forward to your follow up. Do not hesitate to ask for clarification on anything written here.

Can we capture the video and audio using cam and microphone in Edge Animate?

Hi Everyone,
I got a new requirement from the client to create a HTML5 based functionality through which one can capture the video and audio using his web-cam/camcorder and microphone. I have researched on internet and found that there is api available (not reliable) http://www.html5rocks.com/en/tutorials/getusermedia/intro/ . I am not a coder by profession and use Edge animate to create HTML 5 based animations and stuff like that. Another problem which i have found that the api only works well with Chrome and Opera and not with Mozilla, IE..
Can anybody help me out in this, please...
Thanks & Warm Regards
Vikas

Hi, Vikas-
After a brief bit of research, you're definitely hitting upon the limitation of the browsers. Not all of the browsers have implemented this part of the HTML5 standard, so you're going to either have to use Flash or be limited to these specific browsers.
Thanks,

My apple TV is connected to a DTV with an HDMI cable and to my Yamaha receiver via optic cable. We rented a movie on Apple TV and.found that the movie played, but we only got audio for music tracks. Voice tracks were silent using both TV and receiver.

My apple TV is connected to a DTV with an HDMI cable and to my Yamaha receiver via optic cable. We rented a movie on Apple TV and.found that the movie played, but we only got audio for music tracks. Voice tracks were silent using both TV and receiver. This only occurred on the rented video and on recorded shows on my cable DVR. previews and other content on Apple TV are fine. Any ideas??

Previews and trailers do not contain 5.1 audio.
If you have recently moved your setup, you may have inadvertently changed some of the settings on your receiver. It certainly sounds as though it is unable to play the 5.1 audio from the Apple TV.
