Sansa C200 no longer plays through dock

[patrussell]

Just installed Rockbox on my Sansa c200 V1 and noticed that it no longer plays through the dock speakers on my im510.  I saw a few other posts regarding this but could not see where there was a solution.

Has anyone been able to resolve this?  I really like the Rockbox firmware but need to be able to play through the docking connection rather than the line out (it is used for something else in my office).

Any help or ideas would be greatly appreciated.

I don't know much about your particular accessory.  Maybe you could add it to the table HERE.  It looks like the docks/speakers listed there at least play the audio at the line out.  It is possible that your dock expects to communicate with the SanDisk firmware and won't work unless Rockbox sends the right signal.

I will need to go through the registration process to update the chart.  I'll take care of that later.

I saw my dock model in the chart already but it was tested on an e250 and seemed to work.

I do not get any sound out of my c200 player unless I use the line out jack.  It will charge the player while docked, just no sound.

More info is certainly  better, so thanks for updating that table.  Though, I can't think of a reason that a Rockboxed e200 would work with the dock and your c200 will not.  Does the dock work properly with the SanDisk firmware?

A minor and tangential point is that the line out is only located in the dock connector.  The 3.5 mm jack is a headphone jack, not a line out.  So, it seems you're saying you can get sound from the headphone jack, but not from the line out.

You are correct...the headphone jack works fine, as does the Sansa firmware.

I installed the Rockbox firmware using the installer rather than doing a manual load.  Could this make a difference? Maybe an older firmware version would help?

Installing either way should be fine.  One possibility is that for whatever reason there's no signal being delivered to line out.  I don't have a c200 or any accessory that gives access to line out.  I asked on the IRC channel just now and it's not clear if anyone around here has both a dock and a c200 to test with.  I posted the URL for this topic, so maybe someone will read the log and come here to shed some light on this situation.

I'm not opposed to being a test subject if it will help to get this fixed.

TWiki table has been updated for im510 dock and c200.

Thanks!  

It might be a good idea to file a bug report.  Usually, I try to make sure the problem affects multiple users of the same hardware before suggesting this (as an indication that it's not a fluke of a single target).  That doesn't seem like a good pre-condition in this case due to the scarcity of c200 users with docks.
