i have an issue trying to record from an SGTL5000 using 8kHz sampling rate.
The soundquality is very bad, higher samplerates are okay.
I think there is an issue in one of the kernel-drivers.
We are using a custom board with the sgtl5000, installed kernel is 3.14.35 with backported patches from mainline to
I'am as good as possible on the current mainline drivers, except of underlying frameworks.
arecord -D "hw:0,1" -t wav -f S16_LE -c 2 -r 8000 test.wav
I've attachted a sample recording with 8 kHz, it sound like there a missing samples.
And a file with 48 kHz sampling rate, same hw and settings.
Capture-vol: 67, mic-vol: 33, AVC-off, Capture-ZC off.
The hardware is almost exactly the reference from the sgtl5000 datasheet.
Can anyone help me?
Thank you guys!!
