Intel audio & alsa problem

Hi everyone!
first post here in the forums
So as part of a work I'm doing with HRTF (binaural audio) I need OpenAL to use 44100hz. I was using it fine on my previous OS, but in Arch I get this error with all apps that use openal:
AL lib: (EE) UpdateDeviceParams: Failed to set 44100hz, got 48000hz instead
My laptop uses intel integrated audio and graphics.
I'm not sure where I should start to look to find a solution, alsa? snd module? other?
thanks in advance!

Hi there!
thanks. Using some help I got in IRC I added a line in my (previously non-existent) asoundrc, to set the default to 44100. But then I get this error:
AL lib: (EE) GetHrtf: Incompatible format: Mono 44100hz
Which somehow suggests that there is a problem somewhere! I tried playing a mono file with 44100 in audacity, and it worked fine. Its just openal that seems to be having issues...
Also, I dont want to set my default to that in the asoundrc file.

I have an audio810 chip, have you tried my numbers listed in above post 8086,24d5
also here is selected output from prtconf -v
name='compatible' type=string items=7
value='pci8086,24d5.1014.2c7.2' + 'pci8086,24d5.1014.2c7' + 'pci1014,2c7' + 'pci8086,24d5.2' + 'pci8086,24d5' + 'pciclass,040100' + 'pciclass,0401'

This page may give you a solution if the above does not work.
http://blogs.sun.com/PotstickerGuru/entry/solaris_x86_hardware_shopping
In Brief:
Solaris 10 and later supports most Intel Spec AC'97 audio, VIA 823x Audio, and some legacy Sound Blaster stuff. That covers about half of all the audio on most boards these days. There are still a few boards with AC'97 audio which the Solaris included install media won't recognize, and there is the new class of High Definition or HD Audio chips. For folks with an unknown AC'97 type of audio controller/codec combination (read your spec sheet or prtconf -pv and find the PCI vendor and device ID and web search that device to find out what it supports), most likely, you have a good chance if you download Jurgen Keil's audio drivers and install them. Jurgen supplies his own versions of VIA and AC97 Intel audio drivers. These have different module names and will not clobber the existing drivers, and his installation package does a good job of pruning and transferring PCI vendor and device IDs to his driver control where both the Sun drivers collide with his drivers. Jurgen's drivers are especially useful with some AC97 codecs that have a non-standard sample rate conversion hardware. Where the Sun audio810 driver fails, or takes a huge performance hit going with a software sample rate converter (am_src module), Jurgen's driver allows one to compute the proper sample rate and set it as a configurable in the /platform/i86pc/kernel/drv/audioi810.conf which usually gets the driver to play audio at the proper speed. The information on how to do this is actually in the .conf file itself and has come in handy on a Compaq motherboard with Intel 815 chipset and AC97 audio. Jurgen's VIA drivers eat a bit more memory for buffer space, but lower the interrupt rate dramatically, eliminating almost any hiccups on some very slow first-gen EPIA 500 fanless C3 mini-ITX systems and allow those to play flawless audio.
good luck

Premiere CS4 - Audio sync problems, Encoding Problems

Hi,
I've been using Premiere CS3 for encoding 20-25 minute videos to deploy on a Flash Media Streaming server.
Today I upgraded to CS4 and everything that I render to FLV/FV4, H264 or Quicktime format has serious audio sync problems when I use AAC as the audio codec. Unfortunately for me, AAC is the codec that I need to use for the streaming server. The audio is synchronized to begin with, but it gets progressively unsynched as the video progresses.
Has anyone else had this problem? I'm using bitrates of 256 kbps, 512kbps for the video and 24 kbps / 32 kbps for the audio.
Another thing that I've noticed is that many of the options that I used when encoding videos are no longer available!! For instance, I cannot generate hinting tracks for Quicktime, and most of the audio frequencies are gone for Quicktime as well.
What a disappointment:(
-Chris

Seems to be an on going issue with no response from Adobe. Have the same issue with the audio running ahead of the video. (Cool if this was an old Japanese monster video).
Running CS4 PP & AME all updates are current. Nvida Quardro CX (current drivers 4.20.006) used several formats (Elemental h.264 to MPEG-2) same issue.
PC Intel Xeon CPU 3.20GHz 16GB RAM – Prof Win XP x64 Ser Pack 2
Any help from Adobe would be appreciated.

AUDIO SYNCH PROBLEMS

I have never had an audio synch problem 'til now. I am running 10.5.7 on a 2.8 GHz Intel Core 2 Duo 4 GB ram, 24" imac.
iMovie 6.0.4
I have a 50 minute heavily edited project with many transitions, etc.. I have no problem with the footage downloaded from my Sony HD camcorder. I even saved many individual frames as pictures and changed them to the beat of the music in the timeline and all worked perfectly. BUT, my problem is with the "video trailers" I slipped into the timeline. The audio slips when I play back in the timeline AND when burned to DVD. BUT, it does not slip in the same place every time I preview it. If I scrub the playhead back over some of the bad scenes and play them again, they are in synch. IT KEEPS CHANGING..... When I export to a desktop movie to review - the synch problem is there and some of the audio is missing. This only happens on "movie trailers" I have downloaded.
I can't figure out why it keeps changing in the timeline and then correcting itself when I back up and play it over again. I AM GOING CRAZY........
Thanks in advance for any suggestions.
Wally

Thanks for the reply but my problem is not with iDVD - it is with iMovie - when I add "trailers" to it they go in and out of synch at different places everytime I review it before moving on. When I scrub back over the problem area and then play again, they are perfect for one time and then I try again and they are not synched. The problem is in iMovie.
Thanks,
Wally

[SOLVED] Choppy sound with Intel audio card

Ever since I bought this laptop and installed Arch, I have experienced this annoying choppiness.
What happens is that when I highlight other windows, under the minimum memory/cpu load the sound is truncated. I can't listen to music pleasantly on my laptop, and I can't stand it.
My laptop is a HP 530, with an integrated Intel audio card. This is the output from hwd -s:
Sound(a) : 82801G ICH7 Family High Definition Audio Controller module: snd-hda-intel
I have 1Gb of RAM, and the processor doesn't seem very busy when the sound is truncated. This happens under any DE/WM - even in tty!
For what is worth, I had problems with the speakers not muting when the headphones were plugged in, and I have followed the method indicated here.
Thanks for your time.

Auto is the default, it might not be resolving the model correctly (that's the case with my laptop). Try model=hp.
If that doesn't work, you could try turning off power saving:
options snd-hda-intel power_save=0

Itunes wont launch due to audio configuration problem

Itunes won't launch saying there is a audio configuation problem, this started all the sudden no new software added no updates, no configuration changes. I've tried uninstalling and reinstalling without improvement and all other audio programs work fine. any ideas?

This is usually a Quicktime problem, see this article:

How to stop the spinning ball/pizza that is stalling repairs to project on imovie 09? on macosx10.5.8 using iomega and superspeed ext h.d. as storage for the events and projects archive of a wedding video that has had audio sync problems on all share form

How to stop the spinning ball/pizza that is stalling repairs to project on imovie 09? on macosx10.5.8 using iomega and superspeed ext h.d. as storage for the events and projects archive of a wedding video that has had audio sync problems on all share formats (iDVD, mp4, and last of all iTunes). The project label now carries signal with yellow triangled exclamation “i tunes out of date”.
To solve the sync problem I’m following advice and detaching sound from all of the 100 or so short clips. This operation has been stalled by the spinning ball. Shut down restart has not helped.
The Project is mounted from Iomega and superspeed ext hd connected to imovie09 on macosx 10.5.8.
What to do to resume repairs to the audio sync problem and so successfully share for youtube upload?

CS4 Audio Export Problem

Hi
I'm fairly new to CS4 and have picked up an audio export problem, more than likely with a setting of sorts. For some reason when I export to MPEG2 -DVD via the Media Encoder, the video portion is fine as well as any audio that has been placed and edited on tracks audio 1 and 2 in PP. However, if there is additional audio placed on tracks 3 or 4 for example (say a music MP3 overlay) then this does not come out ... only audio placed on tracks 1 and 2 in PP come out. I have checked the obvious like making sure the tracks aren't muted etc but to no avail. Also tried changing from PCM audio to MPEG ... Stereo to 5.1 mixdown ... nothing doing.
Any help would be greatly appreciated.
Thanks and regards

Thanks Harm ... got SnagIt and with a few helpful YouTube tutorials ... am in business. Hunt and John, also thanks ... the other method equally as good. Now, I have attempted to attach my screen shot which should display my CS4 timeline and associated audio monitor windows above. By the way, this was for a wedding and as indicated, you will notice an MP3 lying in audio track 3 which as mentioned is my problem as it is not audible after render via Media Encoder. But remember, the moment I slip this MP3 up into audio track 1 or 2 above ... problem solved. I know there must be something small like a setting gone wrong or incorrect. As mentioned, any help would greatly appreciated.
Thanks to you all.

Audio sync problem with videos imported from iPod Touch

I have an iPod Touch 4th Generation that I used to shoot video at a family birthday party. When I imported the footage into iMovie '11, the audio is not in sync with the video (video is about two seconds behind audio) and there is only the left channel of audio. I verified that the video on the iPod plays just fine--no audio sync problem, both left and right channels work. I just upgraded to iOS 5 on the iPod Touch. The iMac is running Snow Leopard 10.6.8.
As a workaround, I can import the video into iPhoto instead. When I play the video in iPhoto, there are no audio sync problems and both channels of audio can be heard. I have imported other iPod Touch videos successfully into iMovie '11 in the past few months, but this has been the first time these problems have occurred. Any help would be appreciated.

Premiere cannot handle clips with variable framerate.
Your converted clips need to have constant framerate.
Otherwise use a converter like Handbrake.

Mac mini audio output problems

This is similar to a problem that appeared before, but with a different twist.
On 4 July all was well. On 5 July I switched on and there was no "chord" from the Mac. When I collected my mail - no sound from my speakers (which are part of my screen). Logged on to a couple of sites - no sound.
The System Profiler, under the "Audio (Built In)" category, says: "No Built-in Audio." I know that's wrong because it's always worked before and when I plug my headset in it works fine.
When I go to the Sound preferences panel in System Preferences, it finds the headset but if I unplug that it finds nothing.
I tried running the hardware test (by putting in the OS X install disc and holding D during startup.) It couldn't find a problem.
So, as far as I can see, audio output is fine for the USB headset output but not for the others. Is there a simple fix? The nearest Apple store is about 200 miles away and I don't fancy the idea of posting the Mac off.
(And I think it's still under warranty for a couple more weeks.)
Mac mini Mac OS X (10.4.10)

hello mini users with the "no audio output" problem
it seems that there are faulty output jacks in the macbook and the mac mini
there are two things you can try:
i tried everything and began thinking about what new software i had installed. it was "macam" which enables you to use older webcams on OSX. i needed that to use my webcam on skype.
macam installs a file called "macam.component"
if you have the same, do this - take that file out of:
(your hard drive)/library/quicktime - macam.component
and just put it on your desktop
restart, then in your sound pref's choose your audio output (if doesn't work restart again)
the first time i took it out, i had my sound back instantly, another time i had to choose audio output in sound prefs. you kind of have to try different things. after you get your sound back, you can put back "macam.component" to use your webcam.
it seems macam causes the problem, the two can not work at the same time.
the second thing: if you dont have "maccam" try plugging and unplugging output jack a few times and restarting until you have sound.
the problem still could be with the OSX 10.4.10 update / quicktime...or maybe even a hardware problem like others with macbooks were saying (with the red light), not sure.
people with macbooks and who have the red light on, say to use a paperclip to turn off the switch inside.
my mini does not have a red light on. i tried using a paperclip but it doesnt work.
hope this helps, beleive me i feel your pain!!!!
what good is a computer without sound?
extremely annoying problem that i hope apple looks into and fixes

Itunes can't run bc of audio configuration problem

Well I've been using itunes for about 2 years now and just recently i installed the newer version. It was working fine until today when my computer told me ther was some kind of computer error and that i should do a system restore. So i did a restore to about 2 weeks ago which was before i updated my itunes. And then i was getting the message that my itunes was missing files and could not run. So i ran a repair on it and still got the same error. Then I deleted it adn reinstalled and I got the error "Itunes cannot run because it has detected a problem with your audio configuration.
So then I undid the system restore and tried itunes to see if it would work. And I was still getting the same message that itunes cannot run because it has detected a problem with your audio configuration. So then I uninstalled it and reinstalled it and still getting the same message.
Can someone help me out? What problem would it be with my audio configuration? I haven't changed anything. Is there something i can adjust to fix the problem? I'm clueless....

the message is typically produced by a problem with your QuickTime. (itunes uses QuickTime for audio and video playback.)
perhaps let's start with the following document:
iTunes 7 for Windows: iTunes had detected an audio configuration problem
... but if no joy there, try this alternate technique for swapping out your QuickTime:
head into your Add/Remove programs. uninstall QuickTime.
Next, we’ll manually remove any leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
5. Navigate to C:\Windows\system32\.
6. Remove the files QuickTime.qts and QuicktimeVR.qtx.
7. Restart your computer.
next, we'll get a fresh copy of QuickTime into your PC by doing a repair install of itunes.
switch off antivirus and antispyware applications prior to the repair install.
go into Add/Remove and select itunes. click "Change" and then click "Repair".
if the repair install goes through okay, restart the PC and try launching itunes again. does it launch properly now?

Audio Configuration problem detected after install

During the download of the new ITunes version I had a major power failure. I went back and completed the download and after the installation I got an error message that ITunes could not be opened due to an audio configuration problem detected. I went to the Apple site and downloaded a new version from scratch and after the install I got the same audio error. Any Suggestions?

Perhaps this Apple KnowledgeBase article will help:
iTunes 7 for Windows: iTunes has detected an audio configuration problem
Hope that helps.
Forum Tip: Since you're new here, you've probably not discovered the Search feature available on every Discussions page, but next time, it might save you time (and everyone else from having to answer the same question multiple times) if you search a couple of ways for a topic, both in the relevant forums, in the User Tips Library and in the Apple Knowledge Base before you post a question.

Audio configuration problem in iTunes

I am running iTunes 7.1.1.5 (WinXP). When opening iTunes, I get an error message that there "are problems with your audio configuration." In iTunes support, I followed instructions to remove Quicktime then reinstall as standalone (without iTunes). Same problem persists. I will add that same problem occurred about a month ago, but that time the same steps of removing Quicktime, then reinstalling as standalone corrected the problem. Unfortunately, it recurred.

See if this helps:

Audio Capture problem in Mac OS X 10.7.5 in Mac mini(in Silverlight)

I got a mac mini and upgrade Mac OS X 10.6.x --> 10.7.5.
However do not hearing the audio in Webpage using Silverlight.(10.6. version doing well)
So, I found the solve this problem, that is a audio capture problem.( My device does not supported Stereo audio data).
this is the source in audio capture using Silverlight code.
CaptureSource source = new CaptureSource()
                        AudioCaptureDevice = CaptureDeviceConfiguration.GetDefaultAudioCaptureDevice()
                    try
                        foreach (AudioFormat af in source.AudioCaptureDevice.SupportedFormats)
                            if (af.Channels == 1 && af.BitsPerSample == 16 && af.SamplesPerSecond == 8000)
                                source.AudioCaptureDevice.DesiredFormat = af;
                                break;
af.Channels is always af.Channel == 2(Stereo)
--- the question is
How can I caputure audio channel mono?
If couldn`t, how can I transfered audio capture data stereo to mono?
Please answer the question as soon as possible ^^
