Loopy C Visitor	Re:Distorted Audio - 2007/02/05 21:32 Hey Dan, can I inquire to what kind of machine you are using...very specifically? I am on a PB 17" 1.67 HR (the last PPC Powerbook) with 2 Gb RAM. I ask because their was the weird cache problem with the HR (where it would go into a feedback loop for sevral seconds) that a subsequent Tiger update addressed BUT it seems to me that Quicktime 'gulps' a lot more than it used to, like if I am playing iTunes and either open the 'Sound' preference pane, or open a sound file in Safari which uses the QT plug-in, or when system alerts (which are turned off) like the 'Toast' chime rings...these all cause a temporary glitch or gulp. Now I can play several audio app's like iTunes, a DJ rack like DJ-1800, and a standalone synth with no problem but Quicktime seems to not multitask anymore. Unless I am nuts (I had the first PB 17' before) it never did this before. What is your experience?

Dan Mackey Visitor	Re:Distorted Audio - 2007/02/06 08:01 I'm running a dual 867 Mirror Drive Door G4 with 512 megs of Ram. I started using version 1.03 as an audio unit host to monitor Band In A Box files and had no issues. I downloaded this latest version and was very enthusiastic about how it worked save for a few items like not reading tempo variations in midi files. In the last couple of weeks however it has really become unusable. Even as only a host in the first version A busy BIAB style sends it into distortion hell now even when using just the DLS music service units. I recently purchased a MacBook for gigging and I have pulled it off of there just to avoid having this issue crop up. That is a 2.0 Ghz Intel Dual Core with 512 Megs of ram. I use Logic express and the OnStage software from fluge will give me what I need though it's a little more bare bones. Because it links to full logic projects, it reads multiple tempos in the middle of a file as well as audio tracks, program changes and the like. I don't think I have run into any of the cache problems you mention though I haven't analyzed it at that depth either. Hope this is helpful.

Loopy C Visitor	Re:Distorted Audio - 2007/02/06 14:27 Yes, that is very helpful as it has crossed my mind more than once that this was a very machine-specific (my machine model) problem, mainly because of that previous cache problem that only affected the HR. Knowing it does on your completly different machine helps focus elsewhere (and gives me a sigh of relief). If anybody from plasq (rob?) is reading this, has the possibilities of a sync problem been considered. I heard a friends machine do something similar when his interface and driver would lose sync. Is there some code abberation that could be losing sync in RAX? Can you enable any kind of monitor/diagnostic within the program and send it to me to look ar this aspect? Thanks again Dan.

Loopy C Visitor	Re:Distorted Audio - 2007/02/21 03:56 I hope to report soon that I have found the problem. I awaiting a response/request from plasq (via support eamil) and at least a week of correct operation since the problem originally was intermittent (though in the last months it has almost never worked and is working now so a good sign I have affected it).

Re:Distorted Audio - 2007/02/26 08:39 So Loopy C, got in contact with us and let us know he had discovered a possible fix for the distorted audio issues. This is his story:

I always felt that something had changed in my system but just couldn't pin down what.

So...here it is, the culprit I feel has been identified. If you remember my initial forum post I had noted that around the same time as RAX's problems I also was noticing an audio' gulp' under certain circumstances. I was never sure if it was related to RAX's problem but obviously thought it might hold a clue. It was this annoying 'gulp' that I have continously gtried to track that finally revealed the problem.

I owned several iTunes 'plug-ins'. I don't know if you were aware but when iTunes 7 came out it broke all the iTunes plug-ins and sent their developers scrambling. The developer of OSS 3D took the approach of operating completly outside of iTunes with a seperate app. Now, when I upgraded it I understood it to be a app that had to be ran in order to process audio, which was true BUT unknown to me it put a 'daemon' in my Global start-up items...so this 'daemon' did not show in my account start-up items OR my global start-up folder (it was set to 'invisible'!!!). When looking at the activity monitor it appeared completely generic and I always thought it was the daemon for my Logitech mouse (as there was supposed to be a 'daemon' running for it'. Now, about the same time had gotten a software version of my beloved SRS (iWow iTunes plug-in) so it was now my goto for 3d audio fx and I didn't even think about the OSS for some time (meaning I never ran it or went back to their site).

Well, in desperation to find this damn 'gulp' I finally started a 'strip search' of my application support and global folders, taking no prisoners. It was setting my scan to see invisible files AND tracing this generic 'daemon' that identified (I pray!!!) the problem. Removing this near invisible 'daemon' seems to have solved all my audio 'oddities.

Now the funny thing is, when I went to the OSS site to follow up I saw that several days after I had 'upgraded' they recalled that version because it was crashing so many user's audio app's, something that it never did on my machine and the only really obvious symptom was poor RAX.

So my 'test' RAX has not distorted since and I hope to build up my 'sets' again. So alls well that ends well, I feel lucky that I not only have it working again but have it at all given the discontinuation, I hope you guys find a new home for it.

Thanks so much for reporting back what you found. It really is very helpful and I hope it holds some clues for some other users out there.

Thanks again Loopy C.
