OLC Reject for audio codec in a H.323-SIP B2B call involving CUCM & Expressways

In the setup, CUCM is the centralized call controller and expressways are used for firewall traversal. CUCM & expressways are correctly as per the Cisco document. A SIP call from a public internet endpoint to CUCM registered MX300 G2 is successfully connected with video & audio. But a H.323 call from public internet endpoint to the MX300 G2 in CUCM is failing. It is seen in the logs that there is a OpenLogicalChannel reject for the audio codec. I tried with both G711 & G729 from the public endpoint, but the result is the same. Has anyone here faced similar problems. Is there anything that I have look at. Thanks in advance.

Hi Martin,
Thanks for the response. I can look at the firewall. But I would like to understand how does firewall can be a factor here when there is a clear OLC Reject. Is it not confirms that the packets are indeed received and there are some issues in opening the logical channel.
As firewall is not in my scope, I need to make clear reason for the other team to look at.
Thanks.

100% audio codec usage

I've noticed that powertop2 shows two entries for "audio codec". One seems to be my actual audio out and one is just 100% active. I've got laptop-mode instaled with all possible powr savings turned on. The laptop is lenovo thinkpad t410.
That's what powertop2 shows:
100,0% Audio codec hwC0D0: Conexant (exaile )
100,0% Audio codec hwC0D1: Conexant
The first entry goes 0% when nothing plays any sound and even shows some application info.
The second entry is justalways 100%.
That's my `lspci | grep Audio`.
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
01:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)
So, there is an extra audio controller that does not seem to do anyting. In xfce mixer it is just a couple of "IEC 958" checkboxes.
So:
- Should I be bothered with that 100% active codec? My laptop battery seems to be dying (my laptop lasts ~1.5 hours on battery now) and I'm trying to minimize power usage.
- What can I do tho those 100%?

Disabling the relevant kernel modules should help.
Check
lsmod | grep snd
and rmmod + blacklist.
But I'm not sure about this...

Could not download this driver: IDT High-Definition Audio CODEC Driver for Microsoft Windows 7.

Tried to download this driver: IDT High-Definition Audio CODEC Driver for Microsoft Windows 7.
It would not download - said it was not compatble with my operating system.
I run Windows 7, 64 bit.
I'm trying to increse the sound volume from the monitor.
I have increased the sound to 100 from the monitor and in Windows . It is still barely audible. . .

Hello again valens-mom,
Thank you for responding to my post requesting additional information. I can tell you that according to Product Specifications page for your HP Pavilion w2338h is a 23-inch wide-screen HDMI monitor, your monitor has 2 watts oer speaker integrated speakers. A pair of reasonably sensitive speakers deliver the following decibel levels at a distance of about one meter.
Power/ Decibels
2 Watts = 93 decibels
4 Watts = 96 decibels
8 Watts = 99 decibels
16 Watts = 102 decibels
32 Watts = 105 decibels
64 Watts = 108 decibels
128 Watts = 111 decibels
256 Watts = 114 decibels
512 Watts= 117 decibels
1024 Watts = 120 decibels
For Comparison
10db = normal human breathing
60db = normal human conversation
110db = power saw, car horn, shouting in ear,
120db = jet aircraft close by, emergency vehicle siren, rock concert
Now as to whether installing the IDT High-Definition Audio CODEC Driver for Microsoft Windows 7 will give you the audio level you are seeking will depend on what computer you have and what audio drivers are installed. To provide you with more accurate information I would need to know additional information concerning your computer. Is this an HP computer? If it is not the driver question would be better answered by the computer manufacturer. If this is an HP computer could you please provide the product number for it so I can take a look into what drivers work on that computer?
How Do I Find My Model Number or Product Number?
Please if you require additional help in this re-post with the requested information and I would be happy to provide you with further assistance. Thank you for posting on the HP Forums. Have a great day!

No settings for Apple Lossless Audio Codec found in Compressor

For archiving reasons I have to convert many audio files to Apple Lossless (ALAC). So I thought it would be easy using Compressor 4 and and a suitable droplet. I was astonished that here are only settings for the following audio formats: AAC, AC3, AIFF, CAF, MP3 and WAV.
No Apple Lossless Codec in the settings?
Does anyone know how to create ALAC files

Thomas A. wrote:
This setting generates a QuickTime file with the extension .mov
Of course it does. Why would that be a problem? "Apple Lossless" is not a file format, it's a codec.
OK, if I change the extension manually to m4a it seems to be an ALAC file, but I am not sure if it a "correct" one in regard to the specifications.
There is no "ALAC" file format specification. What are you going to use the files for?
ALAC isn't specified at all. The audio codec is called "Apple Lossless", and it is a set of algorithms to encode audio data, and a specification for a bitstream of audio data encoded such. It can be put in various containers, the most common being MPEG-4 and Apple Quicktime, but nothing will stop you from using AVI, .mkv, .ogg or anything else as the container format.
If you're unhappy with Compressor, which only seems to offer the QuickTime container format for Apple Lossless-encoded audio, there might be other tools that will transfer it into another container while leaving the actual encoded data untouched.
Since the Apple Lossless codec is now free, mencoder might work, even for the encoding itself. I haven't checked MPEG Streamclip, Handbrake, VLC or others, which might also offer such options.
Quick tests didn't yield any success, but that doesn't mean it shouldn't work.
An alternative for lessless encoding is the "FLAC" (free lossless audio codec), which is usually stored in an ogg container file. I don't think Compressor offers that, although VLC does.
It seems that the exact thing you want is not readily available (i. e. mpeg-4 audio-only with Apple Lossless audio codec.)

PCM Audio Codec Help

Hello,
I am currently trying to submit a commercial for Comcast cable to be aired. They rejected the spot and asked for me to "resend the spot using PCM" and that the audio codec was the problem.
After reading up on it, I am still confused about how exactly to achieve this.
In general they want either MPEG-1 Layer 2 or LPCM SMPTE 302M encoding. Any help on how to create this would be great.
Thanks

Hi G.
Hard for us to tell you how to adapt your current workflow (to produce an export with audio that conforms to the needed specs) without you first telling us what your existing (or preferred) export workflow is.
Need more details. That said, its hard to go wrong as these settings are generally the default:
If you are using Quicktime Conversion then press Options to bring up the Movie Settings window, and click on Sound >> Settings... Format >> Linear PCM is usually the default.
If you are using Compressor to export an MPEG Transport Stream (or Program Stream) then MPEG-1/Layer 2 audio is the default.
Hope it helps
Andy

Premiere and Media Encoder CC with Cineform(converted files have static for audio)

Hi there,
using Media Encoder CC to convert 7D and 5DMKIII video files to Cineform .avi and all I'm getting at the other end for audio is loud static. Video is fine but audio is corrupt. Anyone run into this with CC? I didn't have this problem before CC.

Do you have the same problem with other AVI codecs? What about non-AVI options?

I am using iMac OS 10.7.2 with Garageband'11 6.0.4. I can't record sound from mixer Behringer X1622USB using USB out. when I connect the mixer to iMac via USB appears USB Audio CODEC on Sound and preferences but no sound from mixer to iMac. Need help.

I am using iMac OS 10.7.2 with Garageband'11 6.0.4. I can't record sound from mixer Behringer X1622USB using USB out. when I connect the mixer to iMac via USB appears USB Audio CODEC on Sound and Preferences but I can't get no sound from mixer to iMac only sound from iMac to mixer. I only can record sound using microphone line in. Please help.

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.

MDP for audio only (on iMac mid2010)

Hi
I wanna buy a iMac 27": 2,8GHz (so it's mid 2010).
The information i already gathered:
Audio through HDMI is possible (at least with the proper Adapter).
The issues with 10.6.4 are solved by 10.6.5.
TOSLink has a limited bandwidth and doesn't work for HD-Audio-Codecs (and i don't want to make compromises).
Here's the thing:
I don't want to connect an external monitor, but i want to send audio through HDMI. If i connect the iMac through HDMI to my AV-Receiver (Denon AVR 1911) will the audio work, even though i don't use the output of my AV-Receiver to connect a TV/Monitor? Or wouldn't the AV-Receiver be recognized by the iMac?
And if it does work:
Do i lose performance because the iMac would export audio and video? Or is it possible to disable video export and use the MDP for audio only?
I hope i explained my problems understandable. (Also hope my english is understandable, too. )
Hope someone can help,
Thanks in advance!
PS: Yes, i know it's not possible to play Blu-Rays on Mac, but I would appreciate
to be able to stream 5.1 PCM to my AV-Receiver.

Thanks RRFS, just a couple of questions for you : Do you (or would you) keep things like sample libraries for Kontakt, Logic (apple loops) and sound design library stuff (80 GBs +) on your internal SSD drive? Also, is your internal SSD your principal (or only internal) drive ? I have an iMac that already has a serial ATA as its principal drive, but the store I spoke with said they could add a second internal drive (SSD) to my system if I want to take out my optical drive. Not sure if it would be worth the cash--probably $250 + for parts and labour for 128 GBs that won't make a huge difference to workflow speed, according to BDAqua.
Cheers & thanks.

Does version 12 support producing video clip with AMR audio codec?

From some documents i used as reference to proceude some videos for my phone Premiere Elements 8 can produce video clips with AMR audio codec. I bought today the Premiere elements 12 but I can not find a way to set AMR audio codec for my video clip. Only AAC audio codec seems available. Is it possible to add AMR codec to 12 version?

Neurona17
Adobe typically supports only current version, and, if you purchased from it, is strict on "within 30 days of purchase": for money back on that current version purchase. I do not believe such a thing as a "change the license for other earlier release such as 8 or 9" exists at Adobe. But, you could ask. If you wish to purchase one of those earlier versions that supports AMR export, you might still find some online.
Is the before import conversion of AMR to WAV a viable alternative?
You wrote
Unfortunately so far I have not been able to generate any useful video clip for my system with this 12 version.
Is this in regard to the AMR requirement or to any video without the AMR audio?
Online I have seen that there is a download for the AMR audio codec. Does your system now show that you have such a codec installed on your computer. If not, I am not sure if download of this codec would place it in the Premiere Elements Publish+Share export settings choices, similar to import of some .avi video codecs. (Sometimes 3rd party codecs can create problem, so proceed with caution if you pursue that AMR audio codec idea.
Please update us on your progress when you get a chance.
Thanks.

USB Audio Codec DEMO driver

Good afternoon. Today I bought a mixer Allen & Heath Xone 42. I am having problems connecting the mixer to my laptop. I use Mac Os Lion 10.7.4. When you connect the system uses the USB Audio Codec DEMO driver. Sound enters the mixer, but is accompanied by a constant beep. Every 30 seconds. This is the way and makes the mixer unfit for entry. Please help me resolve this issue.
on the Internet found several similar complaints. Advised to remove the codec. But how to do it, I do not understand.
In support of Allen & Heath wrote the following:
Mac Pro, Mac OS X (10.7.4)

But this mic is for Mac too. It's says that you "plug and play". I bought this microphone to record my music work at home.
This is the website, It says that works fine with Garage Band but ...

USB Audio CODEC not being recognised.

Hello,
I have my my Wharfedale 802 mixer plugged into my MAC Mini (late 2012), Processor - 2.5 GHz Intel Core i5, Memory - 4 GB 1600 MHz DDR3, via USB however it is not being recognised as USB audio CODEC what so ever. I have also tried searching for this to set the outputs in Logic and it is not recognised there either.
I have just updated my iOS to Yosemite 10.10.2 and also my Logic X does anybody know why my mac is not recognising my USB audio CODEC for an input or output?
Please help.
Thanks

I just posted this problem I had also. The USB audio Codec is for PPC macs only. I couldnt get a PYLE USB cassette deck to work in AUDACITY because it needed that codec.Windows users use this codec for many devices including the one you are trying to connect.
My post in Snow leopard forum:
I have come to the conclusion that this codec only worked on Macs that used PPC chips,not Intel Macs.Apple must have dropped it when switching to Intel.No where on the net can I find anything about this codec on newer mac OS's and newer Macs.
Judging from this user's comment and others,they are working with OSX10.4 or newer OS that has PPC support like the first Mac Pro and other PPC's.I think the comments below answer my own original question.Hope this helps anyone with the same kind of problem with USB devices that need USB audio CODEC.
In Audacity prefs, I selected:
"USB Audio CODEC" for both Input and playback.
I even tried lower sample rates and such. Record button stays grey and readouts don't show any input whatsoever even though I am sending a signal.
Mac is a 533Ghz g4 (Digitial audio) running 10.4.11
It is plug into a USB port on back of machine.

Mp4 converted video file is missing audio codec

I have several avi. files on my computer which were converted to mp4. using videora software. A few of these converted mp4. files then had no audio when I tried to play them on my Ipod. I am confused as to how to add the audio codec back into the video files. Do I have to install this to avi. then convert to mp4., or is there some audio codec which will apply directly to mp4. so they do not have to be reconverted? What is the procedure at this point? Thanks for your help in advance.

First thing to do is find out if Videora supports whatever audio codec the AVI uses.
If it supposedly does, write it off as one of the many bugs with videora and get a different transcoder that supports the audio codec.
Outside of having good knowledge of video production and the right tools-there is no easy way to do what you want.

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp56001-56500/sp56429.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter and start the notebook.
Let Windows fully load - it will automatically load an audio driver, but just let it complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, restart the notebook again.

DP-K
