[SOLVED] Crackling YouTube Audio with latest chromium/chrome-dev

wilberfan · 2013-03-31 01:27:02

I've been getting crackly audio with the latest chrome-dev/chromium and pepperflash (11.6 & 11.7). Other system audio is fine. Firefox (with 11.2 flash) is fine.

Is this a known issue? Is there a solution?

This only happens on my 32-bit Arch install. My 64-bit install is fine...

Awesome. That made all the difference! :-)

Thanks so much!

Interesting - what buffer size does it otherwise use? Try, while playing sound:

cat /proc/asound/card0/pcm0p/sub0/hw_params

512, more details here: https://code.google.com/p/chromium/issu … ?id=178626

That's incredibly low, I'm not surprised the hardware can't keep up.

If they care about startup latency, they should be paying attention to ALSA's period_size, rather than buffer_size - IIRC, it is the period_size that has to be filled with data before the sound can begin to be played.

Usual values (as in the config in my sig):
period_size 1024
buffer_size 8192
