Audio stops on Xrun

[nchouba]

Hi,
Setup:

• Jack: 512 samples /48K
• Realtime Kernel
• Rasperry pi 5 (bookworm through patchbox os)
• Digitak II

whenever I get an Xrun the audio stops. is this expected? is the same happens with other Elektron devices?
ovw logs:
Digitakt II @ 003,002: o2h latency: 16.0 [10.7, 19.4] ms; h2o latency: -1.0 [-1.0, -1.0] ms, o2h ratio: 0.999727 Digitakt II @ 003,002: o2h latency: 15.7 [10.7, 19.4] ms; h2o latency: -1.0 [-1.0, -1.0] ms, o2h ratio: 0.999670 ERROR:jclient.c:56:jclient_thread_xrun_cb: JACK xrun ERROR:resampler.c:448:ow_resampler_compute_ratios: Skipping DLL update (xrun)...

Thanks a lot.

Occasionally, this happens to me too.

I recently added code to improve xrun handling. Perhaps the issue is there. I'll check this.

As a side note and If you don't know, using triple backtics enables code blocks in Markdown. This makes logs much easier to read.

As I suspected, the error was happening in the code to handle xruns. I've fixed it in 7e89555.

However, the xrun handling code to correct the latencies and the DLL calculations is not needed after all since there are no skipped cycles and everything will fix itself after a few cycles. So I have removed all this code in b03f469.

Also, I've fixed and improved the max latencies calculations so that now they are reset when changes in the graph happen as this sometimes leads to temporary increases in the buffer usage, and therefore max latency.

@nchouba, could you try again and report back?
