There seems to be numerous and consistent reports that the audio of the first batch of Raspberry Pi boards produce numerous clicks and popping. There are a number of work-a-rounds on the web, [http://www.youtube.com/watch?v=GoerR5l_Cwc a patch that results in some buzzing instead of "clicks"], and even a kickstarter project that is a dongle that plugs into the board for an attempt at better audio. I wanted to get other's views and inputs on this before I add a new section to the article. In fact, I originally came to this article looking for information concerning this apparent problem with the boards. [http://www.youtube.com/watch?v=eTeUE_NeRDM Here is a video of apparently loud clicking coming through], Perhaps the section could go into how audio is generated on the Rapsberry Pi (i.e. via the PWMs) [[User:Nodekeeper|Nodekeeper]] ([[User talk:Nodekeeper|talk]]) 09:43, 27 August 2013 (UTC)
:The clicking problem was caused by turning the PWM engines on only when analog audio was needed. It was solved with a software update months ago. HDMI audio wasn't affected. [[User:Mahjongg|Mahjongg]] ([[User talk:Mahjongg|talk]]) 12:52, 27 August 2013 (UTC)
== FSF free hardware criteria and Videocore ==
Hi, https://github.com/hermanhermitage/videocoreiv
According to other sources the Pi doesn't fulfill the FSF free hardware critera. Maybe that should be included in the article (or at least be included when it will be). I'm not sure the above link shows any indication that they are making any progress on that (maybe not intented to?). But there seems to be some progress in "freeing" (parts of?) the GPU binary blob (bootloader/firmware?). I haven't waded throught this all open source project but there might be something to report from there. [[User:Comp.arch|comp.arch]] ([[User talk:Comp.arch|talk]]) 10:35, 29 August 2013 (UTC)
:As far as I can tell, the RPF has never even hinted that they would ever be open hardware. Some of their competitors (Odroid, Wandboard) are open hardware, but they have more features and a higher price. --[[User:Guy Macon|Guy Macon]] ([[User talk:Guy Macon|talk]]) 13:34, 29 August 2013 (UTC)
