Hello guys, trying to record from a SGTL5000 with 8 kHz sampling rate gives a very bad audio quality. All other sampling rates working fine. Initially posted at NXP forum: https://community.nxp.com/message/975131 Tested with imx28, sgtl5000 and Kernel 4.14.12. I've attached a recording with 8 kHz, capture-vol was 67, mic-gain 33, AVC-off and Capture-ZC off. Recorded with "arecord -D "hw:0,1" -t wav -f S16_LE -c 2 -r 8000 test.wav". Sounds like there are missing samples.. The microphone is powered from mic-bias and decoupled with a 100nF capacitor. Can anybody help me? Thank you guys! Kind regards, Christian Fischer
