Vista Sound-Probleme

[Fraser]

Hi Leute

Ich verzweilfe fast hier an meiner Kiste, deshalb wende ich mich an euch
Hab mich entschlossen von XP 32 Prof auf Vista 32 Ultimate umzusteigen. Hab zwei neue Platten gekauft, im RAID 0 verbunden und Vista draufgehauen. Alle Treiber installiert und mal angefangen meine Software zu installieren. Bei mir läuft immer was am PC, simpsons Episoden oder Musik etc...

Auf jeden Fall hab ich festgestellt, dass egal was ich höre/sehe (avi, wmv, mp3, ogg, usw.), egal mit welchem Player (hab wirklich alle durchprobiert) und egal von welchem Medium (RAID-Platten, externe Platte, LAN) ich was abspiele, es gibt immer kleine Sound Stotterer. Das heisst alle 20 bis 40 Sekunden ist ein kleiner "Stotter" drin, manchmal auch mehrere Minuten gar nicht. Es ist immer ganz kurz und nicht auffällig, aber es nervt extremst, das Video läuft meistens normal weiter. Bei "Belastung", wie z.B. Installationen werden die Unterbrüche viel länger und heftiger. Der Mauszeiger stockt oft auch noch kurz mit. Ich kanns mir nicht erklären Ich hab nen Leistungsindex von 5.9, an der Power kanns nicht liegen.
Ich hab die neusten Treiber drauf, GraKa-Treiber neu installiert, Realtek HD Audio Treiber neu installiert, BIOS Update gemacht, PCI-Soundkarte ausprobiert, Codecs installiert, Prozesse gekillt, ich bin echt am Ende meines Lateins. Wär edel wenn mir jemand helfen könnte...


Der Sound kommt vom internen Realtek-Soundchip auf dem Asus Mobo.
Ich habe ziemlich viele externe Geräte angehängt (2 HDs, externer DVD-Brenner, 2 Mäuse, Tastatur, Gamepad, Joystick, Cardreader, 2x iPod). Könnte es an Strommangel liegen? Hab n sehr gutes Infiniti 650 Watt Netzteil, aber die zwei ATi-Karten fressen halt verdammt viel Strom.

Mein System:

Intel Core 2 Duo @ 2.66 GHz
4 GB 1066 RAM
2x ATi HD2900XT Crossfire
Asus P5k Mobo

2x 250 GB intern im RAID 0
1x 500 GB intern

Könnte es an Strommangel liegen?

Wenn der PC stabil läuft würd ich es eher ausschließen.

Ist dann der ganze Kram an?Wenn ja, dann könnte auch der PCI Bus am Limit sein, oder ein Addressen Konflikt?--->Sound stottert.

Musst das eben testen, also den PC mal etwas "nackig" machen, 2. Grafikkarte raus und eben mal minimieren.

hat das p5k nich einen ADI soundchip? (AD1988B oder so)

musst mal hier nach einem passenden treiber schauen

Nee da ist ein Realtek ALC883 drauf.

okay, ich bin von der deluxe-version ausgegangen.

Klingt für mich nach DPC Spikes.
Check einmal mit dem Tool ob Spikes auftreten: http://www.thesycon.de/deu/latency_check.shtml
Falls Spikes vorhanden sind am besten im Gerätemanager sämtliche Geräte die nicht dringend benötigt werden nach und nach deaktivieren.
Ev. kann es so auf ein Gerät zurückgeführt werden.
Falls du so nicht weiterkommst empfehle ich XPerf von Microsoft, damit kann man herausfinden welcher Treiber wie lange für einen DPC benötigt. Lange Zeiten können dazu führen dass es zu Verzögerungen bei Echtzeitanwendungen kommt.

Vista hat übrigens keine Hardwarebeschleunigung für Audio mehr, daher ist Windows XP bei Echtzeitaudio unkritischer.

Helfen sollte das wechseln des problematischen Treibers, oder eine andere BIOS Version.
Bei der C't hat ausserdem an einem Intel Controller eine SATA HDD die angeschlossen aber der Strom getrennt wurde solche Probleme verursacht: http://www.heise.de/ct/Abgeschaltete-SATA-Platte-verursacht-Tonstoerungen--/hotline/132116.

http://blogs.msdn.com/pigscanfly/archive/2006/10/09/ISRs-and-DPCs_2C00_-The-Silent-Killers.aspx !!sehr interessant!!

Hardware interrupt service routines and deferred procedure calls can be the silent killers of system performance. ISRs and DPCs are the highest priority code that runs in the system - they cannot be pre-empted by the OS and run to completion. ISRs and DPCs that run too long - or too often - can eat up significant amounts of CPU time and cause overall system performance to suffer. They can cause audio and video glitches, mouse freezes, UI hangs, and any number of other system wide problems.


PS.
Viel Spass in der DPC Hell :biggrin:

Hab mal die Karte rausgenommen und alle USB Geräte ausgeschaltet, immernoch dasselber Problem..

Tatsächlich, bei jedem Ruckler zeigt DPC Latency grosse rote Balken an. Hab mal alle Prozesse, die unter meinem Namen laufen beendet, nix gebracht.. ist wohl 'n System-Prozess. Werd mal das XPerf ausprobieren. Aber danke schonmal!

EDIT: finde mich mit dem XPerf nicht so ganz zurecht. Wie wende ich das richtig an? sehe da keine Graphen oä..

[Exec]

Kopier folgendes in ein Batch File und führ es Elevated (Als Administrator) aus.

echo off
cd \
cd "Program Files\Microsoft Windows Performance Toolkit"
echo stopping running tasks
...
xperf -stop
echo stopped tasks
xperf -on DIAG -stackwalk Profile+CSwitch
echo measuring......... continue to stop collecting
pause
xperf -d temp1.etl
echo merged data
xperf -i temp1.etl -o dpcisr1.txt -a dpcisr
notepad dpcisr1.txt


Ausgespuckt wird dir dann was in der Art:

Ich hoffe für dich, dass der schuldige nicht "Unknown" ist.. in meinem Fall ist dies Daemon-Tools.
Wichtig sind die Treiberaufrufe die lange Zeit benötigen (usecs)

Um dir das Grafische Tool mal anzuschauen kannst du diesen Batch mal als Administrator ausführen:

echo off
cls
cd \
cd "Program Files\Microsoft Windows Performance Toolkit"
xperf -stop
echo rdy to start
pause
xperf -on latency -stackwalk Profile -f

tmpl_1.etl -MaxFile 100
echo logging.........
pause
xperf -d latency1.etl
echo merged file created
pause
xperfview latency1.etl


Ausserdem empfehle ich bei Interesse das studieren der Links aus meinem vorherigen Post sowie der dort verlinkten Ressourcen.
Das ganze geht schon tief in die Materie, musste mich damals auch erstmal einlesen und bis ich was einigermassen brauchbares bekommen hab :biggrin:.

PS:
Auch gerade noch mal DPC Latency auf meinem Vista laufen lassen, hab auch zwischendurch 1000usec Spikes.. (gelb) jedoch keine wahrnehmbaren (Audio)Glitches.

@Exec
Ich bin ja hetero, aber ich lieb dich dafür! :D


Hab trotzdem noch bisschen mit dem DPC Latency Checker weitergesucht, und angefangen sogar Systemgeräte zu deaktivieren. Hatte wirklich praktisch alles deaktiviert bis auf den RAID Controller, und es hat immernoch rumgestockt. Jetzt hab ich nen neuen RAID-Treiber installiert, jetzt läufts wieder richtig smooth :) scheiss JMicron..

Danke euch allen!

Schön dass es geklappt hat.
Ich hab übrigens mit XPerf selber auch nur an der Oberfläche gekratzt :whistle:
