We do not have that on Haikou, causing distorted audio. Before: Running an audio test script on Ringneck, 1kHz output sine wave is not stable and shows distortion. After: 10h audio test script loop failed only one time. That is 0.00014% failure rate.

Setting system-clock-fixed does the job, and now a 1kHz sine wave comes out as actually 1kHz, no matter the sample rate of the source. Testcase: These should sound the same: speaker-test -r 48000 -t sine -f 1000 speaker-test -r 24000 -t sine -f 1000 Also remove the clock link here as having it in sgtl5000 and sgtl5000_codec causes duplicate clock unprepares with associated backtrace.
