Audio and Kernel settings

OK - I've spent all afternoon searching and reading and, either I'm stupid, or the answer isn't obviously out there.
Since I reckon it's probably the former - try and speak slowly for me
I want to use my desktop primarily as an audio workstation - by which I mean I want to run things like ardour and do audio recording/editing etc.
I've got most of the tweaks to my system done - but I'm really not sure what, if any, changes I need to make to my kernel. I'm currentlyu running the stock kernel and things generally seem fine - but I'm not sure if I could improve things.
The linux-musicians website suggests the following changes to the kernel config:
CONFIG_HZ_1000=y
CONFIG_HZ=1000
CONFIG_PREEMPT_RT=y
CONFIG_PREEMPT=y
Is this still necessary with recent kernels?
Any advice/suggestions welcome.

CONFIG_PREEMPT_RT is for the real-time kernel only. If you're doing serious DAW stuff, then you'd probably want (note, not NEED I think) that. Unfortunately, the kernel I use to get rt (kernel26-ice) has just upped to 2.6.30 yesterday and as a result the rt-patch doesn't work, till they come out with a 2.6.30 one.
Best to wait for the proper rt-kernel patch to come out, then use the kernel26-ice PKGBUILD to compile it with the above options. I have the kernel compiled here from a month back, but not sure if there's anyway to send it to you.

I have HDMI connection to the receiver and on to the TV - but no audio from my new Apple TV. I have checked all connections and the video is xlnt. Have also toggled thru every possible Dolby/Audio combination in settings. Help! Any suggestions?

I have an HDMI connection to the receiver and on to the TV - but there is non audio from my Apple TV. Not for movies, music, YouTube etc.   I have checked all of the connections and the video is xlnt. Have also toggled thru all possible Dolby/Audio combinations in settings. Help! Any suggestions?

Hello again Parker -
The basic setup is Digital Cable Box, DVD Player, Denon Receiver/Amp and TV Monitor. To that I added the Apple TV. The Receiver only has two HDMI IN slots (one for cable and one for the DVD) and one out to the Monitor.
[I bought a switcher to toggle the DVD and the AppleTV back and forth but just disconnected the DVD to simplify when I ran in to trouble.]
So now I have:
     HDMI from the Cable Box to the Receiver
     HDMI from the Apple TV to the Receiver (in the old DVD slot which always worked well)
     HDMI from the Receiver to the Monitor
     RCA's from the Receiver to the Subwoofer and the other speakers
In addition I have some backup connections:
     S-Video, Optical Audio and L/R RCA's from the Cable Box to the Receiver
     S-Video from the Receiver to the Monitor
Wait - JUST FOUND IT!
By going thru the excercise to track all of the connections per your suggestion, I found an anomaly when I switched Receiver sockets for the HDMI links. The video moved but the audio didn't. Turns out the monitor was using the optical audio feed from the receiver. So I disconnected the optical audio and the monitor automatically switched to the HDMI audio feed!   Looked promising...
So I first connected an optical audio feed from the ATV to the receiver - Audio! Then I pulled it, but the audio didn't switch to the HDMI feed. It stopped. Would be OK if all I was going to use is the ATV, but I need the DVD player too and I can't use a switcher to toggle between them if I have to unplug the optical audio each time.
This is becoming a career! Any suggestions?

How do I use my web cam to record audio and video? I can get the video to work but no sound.

I want to record both audio and video at the same time. The video works fine but not the audio. I do use Skype without any problems using both.

PwmBoat,
This made me smile, because things like this do make me smile... I never make videos on YouCam, but I did this time, so I could test this one out.
You did not say what webcam software you are using...
======================================================================
Video and audio recording works on YouCam V3.5.1.4606
Make sure you have turned on a working microphone in Settings:
YouCam > Right-Side Settings >
Right-Side, Lower-Right, Select a working Microphone from the Drop down list
AND
CHECK "Capture with audio"
OK
You can also buy (for $38 US) YouCam 5.0 from the Cyberlink.com website and it has audio/video and all sorts of other goodies, too. (They have 3.x as well, but why buy what HP already gives you?)
==========================================================================
I hope this helps!

"Error while trying to sync Audio and Midi"

"Error while trying to sync Audio and Midi" I have been having this problem now and then for some time. Now, I can't run any audio files without a lot of popping. I tried all the suggestions on the support document for this issue. I even downloaded new drivers from Motu for my Express XT Midi interface and my 828MK11 Audio interface. There has been no change. HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEELP!!!!!!
Also, I have tried reseting the 828 to factory default and that does not help.
Jonathan Jenkins

Hi,
I solved my own problem by resetting the factory presets:
Follow these steps to restore the MOTU 828mkII to Factory Default Settings.
Disconnect the firewire cable from the 828mkII
Press the Setup knob
Turn the Setup knob all the way to the right
Press the Select knob
Press the Value knob
Power off the interface and plug the firewire cable back in
Power the interface back on
The same steps can be followed to restore the Factory Default Settings on a Traveler.

[865PE/G Neo2 Series] Memory timings and power settings anyone?

I'm not very good with computers, so I've just played around with the timings on my memory, but have not found one stable setting as of yet.
The memory is brand new and I've tested it for errors on my brothers computer and there's nothing wrong there.
Intensive harddrive usage, dvd playing and intense downloading while listening to music are sure ways to crash my system. "..........Not less or equal" is the most common error message, but there are
many many more.
Oh, maybe I should point out that overheating's not an issue, cause I've good fans and run my computer without sidepanels.
I also like to say that I have the first generation of p4 with ht and 533fsb.
I'm sure there's something I forgot to mention but here below I'll paste the system summary that Sandra gave me.
Would be forever grateful if someone could help me out with the memory timings and power settings for my board. Setting it to "auto by spd" gives me a very unstable system, so no avail there.
I'm running the mem at 2.70 and sometimes at 2.65, since these two settings seem to be the ones with least crashes.
The Memory installed are 4*512mb ,kingston 512 kvr333x64c25 pc2700
The PSU is a Tagan "TG480-u01" 480w
Many many thanks in advance guys.

Thanks for your answers.
Danny: 1. Yes, I've put my memory in my brothers computer, and ran memtest there, and it came out ok, but on mine it crashes almost instantly.
2. Yea, I have 2 fans blowing into the case and one out, so airflow is good, cpu is also cool and seems to be happy ;-)
Geps: I can't say I understand all these numbers but there are som specs here as an example, Tagan TG480-U01 480W ATX
I can't imagine that this psu ain't enough, and if so.....I've been had by the dealer.

Trying to record Stereo Mix with a monitor through my headphones. Using Screenium to record Audio and Video, using Avid MBox Mini with MXL 909 Microphone for the audio through the interface.

Basically, what I am trying to do is this:
Record my screen through Screeenium, record my voice as audio through an Avid MBox Mini (interface) with a MXL 909 microphone to pick up the audio. I have all that figured out. I'm able to efficiently record my audio and screenplay through these instruments and programs. What I am having trouble with is the stereo mix. I am running into a slew of problems here... My goal: Add on the audio of a game that I am playing (for example, Amneisia) so that the audio for my game will be picked up internally, and not through the speakers to be recorded through the microphone. I want there to be no external sound except me talking into my microphone. I also want to be able to HEAR the audio of the game through my headphones (and if possible, myself as well, through a monitor maybe?)
Problems I have run into so far:
-Haven't gotten it to pick up in game audio at all while using headphone. Can't figure this out
-Downloaded soundflower, have the output as soundflower. Not picking up anything, will put all my sound and midi settings at the end.
-When I do record through my microphone, it is only picking up a single channel (left earpiece only, no right channel)
-I have figured out it is NOT the equipment, I use Pro Tools and am able to pick up both channels with my mic, recorded a few tests. It's settings and I can't figure it out
-Trying not to run 16 million programs while running the game, will cause lag.
Summed up:
Trying to record:
-Audio from gameplay of any game I am playing through alternative route of speakers (do NOT want to record game audio through speakers, internally)
-Record voice through Avid MBox Mini and MXL 909 microphone.
-Record screen gameplay through Screenium
I followed a guide that told me to achieve "stereo mix'' I need to download soundflower and follow "X" steps. That is done and these are my current settings:
Audio Midi Setup - Stereo Mix custom Aggregate Device, Soundflower (2ch) selected, Avid Mbox Mini selected, Soundflower Output #1 has 2 channels (1-2), using Avid MBox mini for "Input" in order to record. Using Soundflower AND Avid MBox mini as "Output" in order to hear the sounds and replay game sounds (could be the problem? Maybe?)
Sound Settings - Output Stereo Mix (custom channel) Input Avid MBox Mini (recording)
I'm hoping this isn't too hard to understand.. I'm VERY bad at explaining information regarding computers.. It's hard becuase I don't understand it. I can clarify anything that I am able to, so any help on finding certain things would be greatly appreciated.
My computer: Macbook Pro MAC OS X Lion (11G63) 10.7.5 2.4 GHz Intel Core i7 4GB 13333 MGz DDR3 (If any of this is imporant)

Hey guys,
I tried to do some research and it looks like you need to have an external device and its drivers, such as an external microphone, installed on the computer to record audio that can be saved as a sound file. Another Suggestion is to try an auxiliary spliter for your headphones and external speakers?
What software are you using to record your game?
If anyone knows anything different, please let me know.
Thank you for being a part of the Lenovo Family,
Catie

"error while trying to synchronize Audio and MIDI"

Hello All,
Just got Logic 8... installed (as upgrade from 7)
I keep (consistantly) getting this:
"error while trying to synchronize Audio and MIDI" when in play or record mode... has anyone any ideas regarding a 'fix' or maybe even to point out stupidity on my part re settings; I'm open to comments here and would obviously love to get this fixed/sorted out.
System is basically: G5 Dual 1.8/OS 10.4.10/MOTU 828 Mk2
Thanks in advance.

Hi,
I first did what the manual was telling me but that made no difference as the sync would drop within 5 to 15 bars... very frustrating.
Since my original posting I have spoken with MOTU regarding this Audio/MIDI sync problem. There is evidently a simple reset that needs to be done (that is if like me you are using a MOTU 828 Mk2 interface), you have to toggle through both digital input and output settings in the Audio Control Panel. The problem then goes away.
I hope that is helpful. I think that this probably is relevant to all MOTU interfaces, or is at least worth trying if you are having this problem... maybe other manufacturers too... ?
Cheers, Kick

How to get audio and video in one file

hi...I am "premiere beginner user" and I have a simple question , I think..:)...Every time when I am trying to export media out from my premiere (using media encoder) I get video file and some audio files, but what I need is only ONE file, that contains both (audio and video)..for example , I have edited film in hd quality and I want it to export, I choose h.264 format(make some settings,pal,audio quality...) and when it´s "all done", only "result" I get is one video file and two audio files and they are not together :).....so please help mme anyone..ok and as you can see I am not from english speaking country, so sorry for my english...thanks for help....

There is no indication that something is out-of-sync or the ability to move/slip into sync like in FCE/FCP.
To the best of my knowledge, using match frame and overwriting the video with video+audio (or attaching it as a connected clip if you don't want to overwrite the video, which might have effects applied) is the best way to do this.
You can use the blade tool first in the timeline to get just the section you want to get back into sync. Make cuts so that you have a single clip that needs the audio resynced, select it, and use shift-F to select the original synced clip in the Event Browser. Make sure your play head is at the beginning of this video clip in the timeline. Press option-2, then 'q', and now you have the audio back in your timeline, synced with the video. Delete the old, no-longer-synced audio and you should be set.

Export QuickTime file with new audio and maintain the file size and quality as the original.

I shot some footage for a client yesterday and ran into an issue. To make a long story short I have QuickTime mov files shot with my Panasonic GH4 that have a buzzing sound in the audio track. I have clean audio from a recorder that can be sync'd. Is there a way for me to do this for the client and deliver them as the same QuickTime file but with the clean audio and keep the file size close to the original and not have quality loss in the image?
If so I will probably put all of the spanned clips together from each interview and sync the audio before delivery. I am just not sure which codec will give the client the same quality footage compared to the originals and not have a massive difference in the overall file size. They did request that they be Quicktime MOV files though so that is a must.
I don't see this as an option in the codecs in the export settings in PP, but is there a way to export as ProRes or another MAC native codec that will save them from having to convert it on their end? I am on a PC with Adobe CS5.5 so I am not too familiar with MACs, but from what I understand they would need to convert the files if I sent them straight out of the camera.
I found some related search results for this but they pertained to "Best quality" for export. I am not sure how the varying options work but I don't want to create files that are considerably larger, just not less quality.
If anyone has experience with this it would be greatly appreciated.
Thanks,
Cole

Here's the workflow: I imported the video footage into iMovie '08 and did my edits. Then I exported it (share) to my desktop with compression set @ 740 X 480. Then I used QuickTime Pro to fix the audio track. The file plays perfectly with both audio tracks working. It's a QuickTime file (.mov).
I hope this jars any replies as to why the file when uploaded to my iWeb gallery drops the second audio track.
Hmm,
Jack

How do I import AVI video with stereo audio (and keep it that way)?

Today I just discovered that all the AVI video with stereo audio I've ever imported into a Premiere Pro CS6 project has been mysteriously converted to mono. And I can't find any import setting anywhere that enable me to change this.
Here's the deal...
I've have an AVI file with stereo audio (the file is actually a stereo sound test that I downloaded to prove that I wasn't imagining things). On my hard drive, I right-click and view the properties:
Video
Length: 00:00:36
Frame width: 320
Frame height: 240
Frame rate: 25 frames/second
Audio
Bit rate: 128kbps
Channels: 2 (stereo)
Audio sample rate: 44 kHz
I click on it to play and listen with headphones--everything is playing in the correct part of the stereo spectrum. Then, I import it to Premiere, click the file name in the left content menu, and check the properties, suddenly they read:
Type: AVI Movie
File Size: 1.1 MB
Image Size: 320 x 240
Frame Rate: 25.00
Source Audio Format: 11025 Hz - 16 bit - Mono
Project Audio Format: 11025 Hz - 32 bit floating point - Mono
Total Duration: 00:00:36:15
Pixel Aspect Ratio: 1.0
Sure enough, I drag it into the sequence, listen to it, and it's indeed playing mono. Outside of Premiere, the original source file still reads and plays correctly with stereo sound.
When I import stereo WAVs and MP3s, it keeps the original stereo channels without me having to do anything special. I even just imported the same exact file as a MOV with stereo audio, and it showed up in Premiere as:
Source Audio Format: 44100 Hz - 16 bit - Stereo
Project Audio Format: 44100 Hz - 32 bit floating point - Stereo
What is going on here with AVIs? Am I doing something wrong? Are there settings I'm missing somewhere?
(And before anyone suggests I only use MOV in the future... that's not exactly the answer I'm looking for.)

Thank you for that info.
For video, the codec is MPEG-4 Video (XVID) and for audio it says MPEG Audio Layer 1/2/3 (mpga).
There are two issues with that file:
The first is the Xvid CODEC (not meant for editing), and then the MPEG Audio/MPGA. I would convert that file, to something that is more editable.
Good luck,
Hunt

Error while trying to sync audio and video.

Suddenly out of the blue I'm have all sorts of problems with Logic 8. I keep getting the "error while trying to synchronize audio and midi" error message. Even when I'm just using using the audio side. Do you know of a local logic tech that could check out my system? Might be a problem with my motu 828mk11 audio interface or corrupt drivers, bad preferences. I'm unable to do any work in Logic until I get this problem solved.

(Did you do any upgrades with the Firewire plugged in?)
Usually a MOTU reset will fix this.
Follow these steps to restore the 828mkII to Factory Default Settings.
•Disconnect the firewire cable from the 828mkII
•Press the Setup knob
•Turn the Setup knob all the way to the right
•Press the Select knob
•Press the Value knob
•Power off the interface and plug the firewire cable back in
•Power the interface back on
http://www.motu.com/techsupport/technotes/document.2004-06-16.6405589976/view
If that doesn't work.
1) Unplug ALL cables from the 828MkII.
2) Double check that the power cord is really unplugged.
3. Switch the voltage switch on the side from your setting (110 in the US) to the other setting and back a few times.
4) Make sure you've set the voltage switch back to the right setting for your country.
5) Plug everything back in.

LogicPro 8 "Error while trying to synchronize Audio and MIDI"

Hello,
My rig: Dual 2.5 GHz PowerPC G5 3.5 GB DDR SDRAM. OS X 10.4.11. Logic Pro 8.0.2, Motu 828mkII interface, emagic Unitor 8 midi interface, Makie Control Universal, 7200rpm Firewire 800 Hard drives.
I Just launched a Logic Pro 8 session that was started a few days ago and when I click "Play" there is no audio from the recorded tracks coming through the speakers. All that comes through the speakers is a series of hi pitched (roughly 4k to 6k) beeps and then an error message: "Error while trying to synchronize Audio and MIDI". I've tried restarting everything and still get the same results. I tried switching audio device to "built-in audio" instead of the motu and that works fine, (the tracks play back correctly).
I've also tried other sessions that have different sample resolutions and bit depth and I also tried reseting all midi drivers.
All sessions produced the same results, "Error while trying to synchronize Audio and MIDI", and played correctly when using built-in audio device. It's looking like the problem is with the motu.
How can I trouble shoot this?

Sounds like the MKII needs a reset.
You can reset the 828 MkII to default settings in the following way (as provided from the MOTU support page):
Follow these steps to restore the 828mkII to Factory Default Settings.
Disconnect the firewire cable from the 828mkII
Press the Setup knob
Turn the Setup knob all the way to the right
Press the Select knob
Press the Value knob
Power off the interface and plug the firewire cable back in
Power the interface back on

Solution for "Error while trying to synchronize Audio and MIDI" and "System Overload" messages

Article for those who hate Logic error windows
Seen in Logic Pro 9.1.7 on Mac OS X Lion 10.7.4
and Logic Pro 9.0.0 on Mac OS X Snow Leopard 10.6.5
Logic Pro:
System Overload.
The audio engine was not able to process all required data in time.
(-10011)
Error while trying to synchronize Audio and MIDI.
Sample Rate xxxxx recognized.
Check conflict between Logic Pro and external device.
The search in the help given as follows: overload occurs when you use a lot of tracks and a lot of effects on them, and the synchronization is lost when the selected MIDI track for recording or playback. Yes, this is all that is written in the resources. And here are useful tips that have been found:
The Bounce function allows the entire instrument track to be recorded as an audio file. This bounced audio file can then be used (as an audio region) on a standard audio track, allowing you to reassign the available processing power for further software instrument tracks. For more details, see "Bouncing Your Project."
You can also make use of the Freeze function to capture the output of a software instrument track, again saving processing power. For details, see "Freezing Tracks in the Arrange Area."
These tips - about the timing. About overload - there are no tips, except as "reducing the number of plug-ins" and "increasing latency". Zero useful tips - I got two errors in the test project with a blank audio track with no effects, MIDI drums and standard synthesizer, it was no aux buses, and the entire project was only a single plugin in the master track.
Here is the configuration of my computer:
iMac12, 2
CPU: Intel Core i5 3,1 GHz
Memory: 4 GB
And here's a project that almost immediately stops Logic, all instruments and plug-ins with the init-patch, ie not the most demanding settings:
It's sad.
When this happened the first time, I could start the project only if the empty audio track has been selected, a track specially designed so that you can at least start the project. Then, this problem has evaporated along with the changing conditions of work and I forgot about it until the last case.
I was looking for the cause of the problem in the console and the system monitor for two days, and finally I found that Logic ping to the network frequently. I remembered the exact time of occurrence of the problem, and system logs revealed that the problems began immediately, as soon as I deactivate the service of the Internet.
Solution: enable the Internet, or add a new network service on a computer with no Internet. I just created the Ethernet connection to the ip address 1.0.0.0
Logic immediately began to sing.

Hi gabaghoul
Yes, it worked for me on four different OS and Logic versions (10.6 - 10.8 and 9.0 - 9.1.6)
It does not work in some cases, hard enough to tell in which one, but you can try, it very easy: go to the net settings and create new Ethernet connection to the ip address 1.0.0.0 and connect LAN cable to the port.
Also you can try to figure out what happens in your system while Logic error occured - fot that you just start Console and search "logicpro"
Pay attention to repetitive events in a console and events with suitable timing, not so far from error
The problem may be related to the GUI or system memory, sometimes turning off Safari (or Chrome, others browsers) might help.
