Bass & Treble zeroed after a power cycle?

[RowaN]

Bass & Treble seem to get zeroed after a power cycle. This is the Sansa e200 build (on my e280). All of my other settings seem to remain intact - crossfeed, WPS, etc.

This has been happening for at least a week, if not more. It is still present today - I'm using build r17415-080508

Does anyone else experience this problem? If so, I'll add it as a bug report unless someone beats me to it.

edit - someone descibes a similar but different Bass & Treble problem here:

I'm afraid I am having the same problem on my Sansa E280. If I go into sound settings and select Bass or Treble and change it, all come back to correct settings including Volume. My current build is R17405.

In his code for R17274 he has a note:
* It's basically just a measure to make sure that audio does not clip during
235     * tone controls processing, like if i want to boost bass 12 dB, i can decrease
236     * the audio amplitude by -12 dB before processing, then increase master gain
237     * by 12 dB after processing.

It seems on the Sansa E280 its doing this at power down, but is not returning original settings after the restart of the unit. Is it something to do with the Sansa using the AS3514 Codec? Maybe.

I have the same problem on Iaudio X5!

Again the X5 has a different codec a Texas Instruments TLV320. So they have broken something with the other codecs. Wish I knew how to code.
Oh well I thought things were going to well, Rockbox has been solid for sometime on the Sansa E280. Its a shame with this problem, I'll probably end up getting sore ears from volume set at 0 db at start.
I have updated to current Version R17501 to no avail.
Maybe somebody will look at it at some stage hopefully.

If you want attention from the developers then you should file a proper bug report.  You can cross reference the bug report with this topic to make it easy for people to navigate.

I will point out that my sound settings save fine with r17502 on a Sansa e280.

Maybe try clearing your settings and see if that improves this behavior.

I will debug this tomorrow, as it seems it is my fault 
Stay tuned...

Please check latest svn version.. should be fixed now.

Hi Christian
I have checked on my Sansa E280 with the latest version R17547 and indeed everything is fixed. Thanks very much. Have fun coding.
