Aggregated audio device problems

Hi, I wonder if there is anyone who can help me?
I would like to combine two firewire audio devices (a MOTU 896hd and MOTU 896) to enable me to use 16 audio inputs into LOGIC 7 (7.1.1) Mac OSX v 10.4.10
I have tried aggregating devices in the Audio and MIDI setup with no success at all!! I followed the instructions that I had been given to use the aggregate device tab within the LOGIC AUDIO INTERFACE page (within logic) but all to no avail
I have organised the setup as follows
1. The 896HD is the first in line.
2. I have daisy chained the second interface from the 896HD to the 896 via a firewire cable.
3. I have clocked the devices via word clock
4. Both interface work on their own but not as an aggregated device.
Is there anything obvious that i'm doing wrong?
I would be very grateful for any help at all.
Best wishes

when I play any sound , the first part of it can't be heard .. for example , when the system start "any sound clip" .. the sound will start from the middle of the voice clip i.e. " the first part of sound is missing" .. but if i repeat the sound it will play without any problem , but after some seconds .. the problem appears again
I tried to update the driver but it didn't fix the problem
BUT when I uninstall IDT high definition driver , this problem become less frequent .. but it still there
I had also recoverd my system , but there is no benifit .
I noticed when I use the head set the problem will deminish completly

MSI Mega 180 Deluxe: "No Audio Device" problem

MSI PC 180
AMD Athlon XP 2600
2 x 256 Mb DDR 333 Kingston
MSI TV Card
1 HD Maxtor
1 LG DVDRW
Windows XP SP2
Norton Antivirus 2004
The computer workest fine until today: now there is no sound.
The device manager show
- NVIDIA NForce Audio Codec Interface
- NVIDIA Nforce MCP Audio Processing Unit
Correctly without yellow o red marks
However in Control Panel , Audio Devices appear: "No Audio Device"
When click in Nvidia Mixer say that there are no audio device
I upgrade to the latest Nvidia unified drivers with the same result
What happen? How i can have sound again?
Regards,

Thank to everybody for the answers
I have reset the clock and the problem continue
I have uninstall the newest drivers (downloaded from nvidia web) using Add/remove programs, and reinstall using original CD from MSI, and the problem continue
The problem is not temperature. The sound is disabled after hours of computer is off.
I unplug the power and the problem continue
Now i have the following audio drivers:
- Nvidia Audio Codec 6.14.348.2
- Nvidia MCP Audio Processing 6.14.348.2
The problem is: The Windows XP detect the integrated NVIDIA sound card and install the drivers but in Control Panel show: No AUDIO DEVICE. And the sound is off...
My conclusion is MSI PC 180 is very weak: the integrated components are very unstable.
I'm computer assembler and i discontinue to sell this MSI equipment.
I'm very annoyed with MSI quality.

USB audio device loses output connection

I use a MobilePRE USB interface and had no problems until recently. My iMac is set to never sleep but if I do not use the computer for a few hours the output from the MobilePre is gone.If I change to the driver to the internal headphone output on the Mac all is fine but in order to use the MobilePre as output I must restart, then it is fine until the next day or a few hour later.
The same time that this problem developed, about a month ago, I also noticed a low level snap or popping sound. This happens through my external speakers and is triggered by any sound activity approximately 30 seconds later. It even happens with the volume turned all the way down and sounds like a connection is being made. Like I said these two problems started about a month ago around the time Apple was sending a lot of updates. I have read a long thread on the OSX forum and know this is a pervasive problem with no solution yet. I mention it here as a curiosity as it started around the same time as the USB audio device problem. My hunch is that it has something to do with a recent update.
I don't think this is a GarageBand problem because it is the same no matter what software is outputting. I ask on this forum because there some knowledgeable audio heads here.

Check the archlinux news item which calls for an entry in kernel commandline .................

In-built Audio device not found

Hi Guys,
My macbook pro suddenly finds no audio device inbuilt. And i can play no sound nor hear start up sound when switching on mac.
I get a 'no parking' like symbol beneath my audio options.
I've tried rebooting in safe mode, Resetting PRAM, Repairing permissions in disk utilities, use my ipod touch headsets, headphones.. NOthing worked.
And i'm feeling deaf whenever using Mac now.
Is there anyway to get the audio back ?
Thanks,
Raesh

Hmm.. Okay. Would give it a last try.
And I have a couple question before doing that..
1. I did the hardware test and It gave me this error .. " 4SNS/1/C0000008 :TPCD--24 "
But When i looked up for this error, it tells me a sensor problem. Not as Audio device problem. Do you think this hardware error of 'sensor' has something to do with audio ?
2. So in-built speaker isn't working, plugging in headphones cable isn't working. But i was wondering whether a bluetooth speaker would be recoganised in the system preferences > audio output device ? Will it work ?
Because i keep on reading that an " in-built audio device not found " problem is a huge one and it costs a lot to repair. They often provide solution of changing the whole logic board (Keeping fingers crossed). And with my warranty period over, I don't wish to go through that path. So want to know if external bluetooth speaker has a chance to get recoganised as an audio device, Then I would buy JBL bluetooth speakers. It seems good and less pricey than changing the whole logic board.
Let me know which way i can go, Thanks in Advance Man.

HP High Definition Audio Device Code 10 Error -- Causing HDMI Sound Problem

Hey guys, my laptop is an HP ENVY TouchSmart m7-j010dx Notebook PC, running Windows 8.1.
When I connect my laptop to my LG Smart TV through HDMI, I cant change the playback device to play the sound from the TV. The HDMI option does not appear in ¨Sound¨.
When I look in Device Manager, under Sound, video and game controllers; the High Definition Audio CODEC has an error which says (Device status):
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
I have tried reinstalling and updating the drivers, cleaning and defraging the registry, optimizations etc.
I followed steps from other posts with similar problem as mine and nothing seems to work, I do not want to reinstall my windows just for this! I am running out of options, I tried everything I could for the past week. I would really appreciate some expert advice.
Thanks!

Fire Wire Audio Devices (M-Audio, MOTU etc) - Problems

This problem is discussed already. But only in connection with Bootcamp.
Apparently, there is a problem with the new FW Controllers uses in newer Apple models. Opposed to the traditional Texas Instruments controller, the new one create problems with FW audio devices. There is a big discussion on the RME page on that (without conclusive result, however). But I think the problem is more general and needs to be addressed:
Here is my problem: New Macbook pro, my M-Audio FW 1814 worked at the beginning )only garage band= with the beta version of the OS X 10. 5 driver, but than failed. Updated driver of m-audio )released end of april, did not help. My apple seems to recognize the external device, the software mixer shows movements, but there is no sound whatsoever coming in or out. Same with MIDI.
My question: Did apple give any statement on the problem? A lot of customers buy apple for making music, after all.
Cheers,
P

Yes, if you setup an aggregate device in the Audio Midi setup of your Mac combining the two FW devices. Open the Device editor->press "new device"->name it->choose the available devices in the menue below->hit ok/done/"fertig" (in german)->select this new device in Logic preferences as your Audio device

There's a problem with your audio device.

Please help. I don't know what the problem is!

i cant figure out what to do, everytime i call someone, it says "theres a problem with your audio device."

HP ENVY TS 15 Notebook PC: Problems installing audio driver (High Definition Audio device)

Hello all,
My product is the HP ENVY TS 15 Notebook PC.
Product number: E3B65PA#AR6
OS: Windows 8.1 64-bit
A few days ago, I upgraded my windows from windows 8 to windows 8.1 and found that no sound coming from the HDTV when connecting my HDMI cable however video is perfectly fine. I was completely baffled because the audio was working perfectly fine before upgrading to Windows 8.1. I have tried several solutions posted on other forums, such as installing other drivers, and uninstalling the IDT High Definition Audio Driver and then scanning for a hardware change. I have checked the HDMI cable and it is working fine with other laptop.
Device manager is showing 2 device :
High Definition audio device ( Showing yellow traingle)
IDT High Definition Audio CODEC
When I am opening the properties of High Definition audio device it is showing :
This device cannot start (code 10)
{Operation Failed}
The requested operation was unsuccessful.
If anyone knows how to fix the problem, please help me
thanks in advance
This question was solved.

Hi:
The IDT audio driver (notebook speakers) appears to be working fine.
The problem is probably with the Intel graphics driver which controls the HDMI audio.
My recommendation would be to install the latest Intel graphics driver from the link below and see if that fixes the problem.

Tomahawk Player - Sporadic "Problem Accessing Audio Device" Errors

Hi, I have recently started using Tomahawk Player in GNOME and some songs from external sources can play and others receive an error that states:
"Sorry, there is a problem accessing your audio device. Make sure you have a suitable Phonon backend and required plugins installed."
However, I have phonon, phonon-gstreamer, and phonon-vlc installed.
How can I further diagnose this?
Last edited by bdamos (2014-11-30 19:48:16)

Hello,
That is unfortunately a not-very-helpful error message as it could mask a variety of problems. One of those problems is that it might happen if Tomahawk is unable to play the url for the track---what source has it resolved to? (rightmost column)?
Feel free to come ask us on Freenode (#tomahawk) and our forums on forum.tomahawk-player.org. You'll probably get a better response there.

Master gain problem with Direct Audio Device: distorted sound

Hi everybody,
I'm in a bit of a fix here. I've got an application that plays music. Developped with 1.4.2, got it working.
However, when I run it with the the latest 1.5 release (5.0 update 6), the sound is distorted. More specifically, though I'm not entirely sure, I'd say it's the bass that gets distorted. By "distorted" I mean it's shrieking, scratching instead of... well, sounding.
I'm using the FloatControl.Type.MASTER_GAIN control to change the "volume". Since it's playback, I'm using a SourceDataLine, and that one ain't got no VOLUME control. Now the problem only appears when I'm amplifying the audio data, i.e. when the MASTER_GAIN's value is greater than 0.0 decibel.
Inverstigating a little more, I found out that 1.5 is using the "Direct Audio Device" Mixer as default as opposed to the "Java Sound Audio Engine" used by 1.4.2. If I force the use of the Java Sound Audio Engine with 1.5 (getting the line from the appropriate Mixer), the sound is OK. However, since the application is intended to be cross-platform, I'd prefer not to impose any such specific behaviour (plus the performance of the Direct Audio Device is twice as good).
Tested on Linux version 2.6.11-1.1369_FC4 and Windows NT.
Looked at www.jsresources.org, but didn't find any information specific to this problem.
Bugparade: no hits.
I'd be glad if anyone could help me on this.

Nobody ?
It narrowed it down to the following testcode. Please try to run it with Java 1.5 and some compatible audio file (a WAVE file, for instance):

Problems with sound drivers - audio device on high definition audio bus

i turned on my computer one day and the sound was gone. no "speaker" icon in the lower right-hand corner of the screen; no choices available via the "control panel: sounds and audio devices" icon. when i went to device manager, i saw "audio device on high definition audio bus" had a yellow exclamation mark. i saw some sites suggested downloading the realtek high definition audio, but that didn't seem to work -- and now i don't see the audio device on high definition audio line either.
any ideas? from what i've read, i gather this is a somewhat common problem but no solid way to fix this. i know something similar has happened to me a year ago but i was able to fix it somehow.
Solved!

Hello,
Have you tried installing the latest audio device drivers for your ThinkPad? If so, did that solve the problem?
