[alsa-devel] VT1708 clicks & pops

[Forest Bond]

Hi,

I have two boards with a VT1708:

* VIA EPIA EX15000G
* VIA VB8002

I'm using VLC to play audio via PulseAudio to the analog outputs.  The VB8002
sounds great, but the EX15000G has random pops and clicks in the output.  Both
machines are running exactly the same configuration (they are using the same
pre-built OS image).

I've tested on the EX15000G using a few different driver versions.  One is
essentially the version from Ubuntu 10.04, but rebuilt due to unrelated kernel
changes.  The other is alsa-driver snapshot
alsa-driver-1.0.24.72.g7c48f.1314.geb1d0.

You can find output from alsa-info.sh as follows:

EX15000G (using Ubuntu 10.04 driver):

EX15000G (using driver from alsa-driver-1.0.24.72.g7c48f.1314.geb1d0):
http://www.alsa-project.org/db/?f=d0265991ec3e975820dc439470aea1df925ca1db

VB8002 (using Ubuntu 10.04 driver):
http://www.alsa-project.org/db/?f=611cc772a3fab7552bbda193b6ad7998f66a60fb

Any ideas what the problem might be?

Thanks,
Forest
