Hi,
I encountered some issue with my USB audio device and couldn't find any similar issue in previous mailing lists, any help will be appreciated.
When playing an audio stream using MPlayer Ver1.0rc2-4.1.2 (tried different sample rates 44K, 48K and different files WAV , MP3) using my Creative SB0271 USB device on ARM based system(Marvell Kirkwood SoC) and kernel 2.6.22.18, I hear an interfering constant noise additionally to the original audio stream.
At the beginning I heard this noise also when I used aplay(for WAV) but after I reinstalled the ALSA-LIB and ALSA-UTILS(version 1.0.14rc4), the aplay suddenly started to work smooth.
I tested different USB audio device(AKM) but got same noisy results.
Another piece of information I can provide is that increasing the CPU utilization eliminates the noise completely - maybe a timing issue ???
Any ideas ?
Thanks,
Eran.
