Google chrome interrupts audio...

post #1 of 19
Thread Starter 

Hello.

I'm having a problem with Google chrome; If I'm listening to audio from iTunes (via Bluetooth headphones, or wired headphones to FiiO E09/E07 combo) the playback stutters if I do anything in Google chrome (e.g. open a new tab, or click on a link within the page displayed). 

Any ideas?

Thank you.

I presume you might be running out of RAM, I had a similar situation watching videos and surfing at the same time. What are your laptop specs?

It's an HP 'all in one PC', AMD Athlon X2 260u, 1.80 GHz processor, with 4GB RAM (and I've Readyboost going...), running Windows 7 64 bit.

Thanks for the reply!

Has anyone got any ideas about this - it's driving me mad. I listen to iTunes via Bluetooth or amp/dac and cabled headphones, and any internet browsing interrupts the audio...help?

Try using LatencyMon to find out what is causing it, it could be a driver than needs updating\downgrading.

Thank you. Just trying this - but I don't really understand what I have to do - it suggests 'disable CPU throttling settings' in control panel...I've looked but...? Once again, thank you for your help.

Could you attach a screenshot after you click the green play icon (main screen). Also take a screenshot of LatencyMon when you are browsing with chrome.

I might be a NIC or WLAN driver thats causing the problem.

I'm sorry, i can't get a screenshot, I have tried...Latency Mon says - 'Your system seem to be having trouble handling real-time audio and other tasks. You are likely to experience under runs experienced as dropouts, clicks or pops. One problem may be related to power management, disable CPU throttling settings in control panel and BIOS setup. Check for BIOS updates'. Thank you for your time!

click the green arrow, browse in chrome for 10 seconds, then click the red stop button. click stats and then copy and paste the same 2 sections like below.

Did you disable the CPU throttling as suggested by LM software? Any impact?

 

Probably it's GUI handling for Chrome that's making issues. Is the GPU sharing IRQ/resources with audio/BT devices (you can check this through device manager)? Is there a setting for graphics hardware acceleration you could change (turn off)?

Also can you give us the exact model number for your HP

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. 
LatencyMon has been analyzing your system for  0:01:05  (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs):   16020.890923

Thank you for your help

Ok it looks like something with the NIC or WLAN. When you have the problem are you using wireless or a Ethernet cable to connected to the internet?

Ethernet cable...
