Google Chrome freezing and beep

I upgraded Chrome from 43 to 46 on PC. When open new page, it freezing for 3-5 seconds randomly, sound ‘beep’, then normal…

But Chrome 26 to 46 at Thinkpad x200 work fine, no freeze happend! Maybe hardware problem or driver mismatch.

I ask Google for a long time (3 days:), found this post
https://code.google.com/p/chromium/issues/detail?id=259165

They said Realtek HD Audio Driver have some bug, will let chrome crash, need to install newest driver. My PC have Relatek HD Audio, x200 is Conexant CX20561, so I download newest Realtek driver. After I install the newest R2.71 driver, freezing happen less, but still happen……

So I try this:

1. Uninstall Google PinYin Input.

2. goto chrome://flags/#try-supported-channel-layouts

“Causes audio output streams to check if channel layouts other than the default hardware layout are available.”

Enable.

Then it will look like:
chrome_freezing

3. goto chrome://settings/

Uncheck “Prefetch resources to load pages more quickly”.

Uncheck “Using Hardware Acceleration when available”.

And freezing gone:)
