Phone crackles when playing audio

[Cali3350]

Hey guys,

Just recently updated to DLo0 Superclean and ever since my audio is a little crackly when playing either native music or pandora. Obviously the rom is suspect, but I am confused why it would matter as the kernel is the same as stock, and it shouldn't be affecting processing. Anyone have experience with this?

Use the search button. download Setcpu and set min to 200. You're welcome.

I had audio popping on DJ05 and DL09 but using set CPU and setting min to 200mhz fixed it.

I see. Thank you, and my apologies

Out of curiosity why does this present only with the superclean ROM? This seems like strictly a kernel issue, something that wasnt modified.

for anyone who needs it: SetCPU

Out of curiosity, does anybody know WHY changing the min CPU speed to 200 helps? Is it because the default min CPU is 100Mhz, and isn't fast enough to keep up with audio processing?

Almost def, thats why im wondering if the new kernel is more aggressive in its clock settings.

I would say that it's due to 100mhz being to low and the scaling being setup so that it doesn't cross the threshold to be bumped up to 200mhz. That, or it's going just up to the threshold, then lowering some, and constantly going back and forth between 100/200mhz.

Yay my first post. Anyways, were you using the Adrynalyn kernel? I'm new to all this rooting and stuff since last night. I tried the Adrynalyn + superclean dl09 and I got some crackling and popping.

I was a bit stumped but I tried a different kernel and the popping is gone. Right now i'm using Stupidfast. so far so good
