Sansa Clip+: noise when reading from micro SD card

(1/3) > >>

tempe:
hi everyone,

my clip+ always makes a noise comparable to a disturbance every time it accesses the sdhc card. any suggestions? i'm using the current release.

bertrik:
Can you please state the *exact* version and build number?

How loud is the noise (approximately)?
Does it depend on the volume level? Like at what volume level is it very noticeable, and at what volume level is it neglible?

What kind of AMSv2 "variant" do you have? (see menu System / Debug / View HW info)

What kind (brand, speed class and capacity) uSDHC do you use?
Do you have another uSDHC card to test? Does it show the same problem?

Do you also hear it when accessing the internal storage?

What kind of headphones are you using?

hi bertrik,

1. 3.8.1, it's the release version. i dont know how i can find the build number.
2. hard to describe... it's well audible at low volumes (or with volume turned down completely). it does not depend on the volume level (it doesnt get louder if i increase the volume). from -45 db and up it's neglible.
3. AMSv2 variant 0
4. kingston micro sd hc 8gb, class 4
5. yes, also with a 2 gb micro sd where no brand is printed on. way less audible though.
6. yes, also with internal storage. way less audible though.
7. earplugs sennheiser mx-400 (i think)
btw: no noise with the original sansa firmware

bertrik:
Can you try the latest patch in http://www.rockbox.org/tracker/task/11907 ?

tempe:
first of all, this seems to be exactly the problem i'm having!

but... i'm sorry i'm no programmer and i've never applied a patch yet. afaik after looking in the simple guide to compiling, i have to install a compiler software and deal with the source code and put in patches there and compile them, which seems a difficult thing (at least for me). isn't there an easier way?
