Title: U12 and Priority Post by: Leo on April 06, 2008, 10:24:44 am G'day Peter,
with U12 XX will not start anymore for me with realtime and low as priority settings (both with Vaio double core and Asus single core pc). I have been able to use the realtime and low settings as far as I can remember. Now I have to luse the less éxt'reme settings. So is u12 more demanding for the PC ? Also when I (secretly of course) try to upsample I get that upsampling is not possible for 88.2 files and I get this with just standard 44.1 wav files. I know you don't believe in upsampling but these are strongarm politics for sure Peter. Leo Title: Re: U12 and Priority Post by: PeterSt on April 06, 2008, 10:37:22 am Het Leo,
The Upsampling not working is unintentional of course, and what I get from others is that you should lower your DAC Is setting (to e.g. 96K). I didn't try that myself, but obviously the message is (still) tripping on wrong data. I can ensure you that it works, if you only have the right settings (hence those are abusively anticipated upon). Quote with U12 XX will not start anymore for me with realtime and low as priority settings What do you mean "don't start anymore" ? Note that if you by accident switched the advised prio settings (like setting ThreadPrio to low) it is true that indeed Engine#3 won't start anymore. This changed a few versions back, and is intentionally (and mentioned in the Release Notes concerned). Otherwise, yes it is true that the latest versions seem more demanding (which proves the good btw). ? Title: Re: U12 and Priority Post by: Leo on April 06, 2008, 11:24:35 am When I set the DAC in XX to 24/96 it will play but at half speed, with my Altman at 44.1 kHz. The Altman will not recognize the data at 88 kHz The Altman dac rate has to be switched by hand.
Before I could even get 176 kHz with quad upsampling , with the same files and equipment. I played before as long as you included the possibilty with Player prio at Realtime and Threadprio Low. U12will just not start to play, even when I wait for minutes, after I while I get the message that XX did not start within expected time. One step down respectively up for both prio's will give me music again. I never had this before as far as I recall. Also the single core PC will have lot's clicks and stutters at Q1 -2, it has to be higher to have uninterrupted music. I now play with setting 14 Title: Re: U12 and Priority Post by: PeterSt on April 06, 2008, 11:41:22 am Quote When I set the DAC in XX to 24/96 it will play but at half speed, with my Altman at 44.1 kHz.

I am sorry Leo, but I can't get what you are actually saying. Maybe it isn't even necessary to make it more clear to me, because I just know something is wrong here. I will solve it.

Did you find the Release Notes I was referring to ? This is from 0.9u-5 : Quote Important : As an implication it is not possible anymore to run Engine#3 with ThreadPriority Low (Settings Area). Most probably people did not use this lowest setting anway. But, I obviously now should prevent you from being able to set this. Quote I never had this before as far as I recall. Also the single core PC will have lot's clicks and stutters at Q1 -2, it has to be higher to have uninterrupted music. I now play with setting 14 This is from 9.9u-8 : Quote This version is prone to require more from the OS, and therefore may show crackling at settings (Q1, Prios, Core Appointment) where you didn't have it before. Please take good notice of Vista shutting down services, and try to get the grasp of when this happens (usually shown by a message and the spooler system often being the first); you should not leave that message be, but click it away. If you let it be, then crackling almost sure will start to emerge, and it will get worse and worse. When you want to do it right, click away the message, and Stop/Start playback. Usually this is not necessary, but you have to get the hang of things a bit. Try to think of Vista needing some settling time for her new situation (without the shut down service). Does it make better sense now ? Title: Re: U12 and Priority Post by: Leo on April 06, 2008, 12:22:24 pm I missed that part of the release notes. Now it is solved by the Thread priority at Below Norm, and I can play with Realtime. Thanks.
And the other point about replay speed was caused by the FF which had as masterclock and still at 44.1 kHZ. Blush. Excuse me. So I only miss the possibilty to go to quad upsampling with U12.... Title: Re: U12 and Priority Post by: PeterSt on April 06, 2008, 12:44:38 pm Quote So I only miss the possibilty to go to quad upsampling with U12.... I just tried (without sound because I'd have to reroute cables for that) ... when you set the DAC to 96/24 it just works. It does NOT work when the DAC is set to e.g. 192/24. This is a matter of the inappropriate error messages. Note that with setting the DAC to 96/24 this does not imply you can play 96KHz only. It is merely a self protection from setting things wrongly, and in some occasions it's really doing something. So now you can mis-use the 96/24 setting to allow for Quad anyway. PS: Don't forget to set the FF to 128 samples for that. Title: Re: U12 and Priority Post by: Leo on April 06, 2008, 12:53:31 pm But the quad box is greyed out when DAC is set at 96kHz :)
Title: Re: U12 and Priority Post by: PeterSt on April 06, 2008, 02:00:42 pm I checked Upsample instead of Quad. :swoon: :fool:
Sorry ... Will solve it ! Title: Re: U12 and Priority Post by: Leo on April 06, 2008, 02:16:08 pm I am sure you will
