[BUG] alsabat test failed with 821Hz on IPC4 nocodec platforms #7285
Description
Describe the bug
This issue only happened on IPC4 nocodec platform with 821Hz sine wav. From the waveform, there's a glitch and it seems that one sample point is inverted. No such issue with 599 or 997 Hz
To Reproduce
~/sof-test/test-case/check-alsabat.sh -p hw:sofnocodec,0 -c hw:sofnocodec,0 -C 2 -F 821

Environment
- Branch name and commit hash of the 2 repositories: sof (firmware/topology) and linux (kernel driver).
- Kernel: tip sof-dev
- SOF: main
- Name of the topology file
- Topology: sof-tgl-nocodec.tplg sof-adl-nocodec.tplg
- Name of the platform(s) on which the bug is observed.

We have a duplicate, internal issue 379

The sine frequency should make no difference to the result, is the glitch periodic or just random in position/channel ?
keqiaozhang commentedon Mar 20, 2023
Just random in position/channel, no rules.

@singalsu how can we make the CI testing more clever to reject glitches on the USB testing HW ?
singalsu commentedon Mar 23, 2023
I'm making a proposal for additional glitch detector with Octave to check the alsabat recording, since alsabat may miss some issues. The test is for measuring presence of a test frequency, not really to find poor audio or glitches. But it will also support ignore of start ramp that can now trigger alsabat. If it works we can relax a bit alsabat and rely more on the additional test.

@keqiaozhang we need IPC logs with payloads to reproduce with FW tests, could you prepare?
juimonen commentedon Mar 28, 2023
anyone able to replicate this locally? I just can't reproduce in my upx...
keqiaozhang commentedon Mar 29, 2023
I did a quick check on TGL-UP and ADLP-RVP nocodec devices, it seems that this issue no longer exists on these 2 platforms.
lgirdwood commentedon Mar 29, 2023
ok, pls close when happy its not in daily test.
keqiaozhang commentedon Mar 30, 2023
This issue no longer exists in CI, closing this bug.
