I've reformatted the lines to make it easier to read.

pi@moode:~ $
Apparently there was a USB audio device (D30) configured but when this log was generated it was either off or unplugged. Thats ok and the response during startup is to reconfigure to HDMI 1.
Here's the code block in worker.php that does that.
Code:} else if ($actualCardNum == ALSA_EMPTY_CARD) {
workerLog('worker: ALSA card: is empty, reconfigure to HDMI 1');
$hdmi1CardNum = getAlsaCardNumForDevice(PI_HDMI1);
$devCache = checkOutputDeviceCache(PI_HDMI1, $hdmi1CardNum);
// Update configuration
phpSession('write', 'adevname', PI_HDMI1);
phpSession('write', 'cardnum', $hdmi1CardNum);
sqlUpdate('cfg_mpd', $dbh, 'device', $hdmi1CardNum);
phpSession('write', 'alsa_output_mode', 'iec958');
phpSession('write', 'alsavolume_max', $devCache['alsa_max_volume']);
sqlUpdate('cfg_mpd', $dbh, 'mixer_type', $devCache['mpd_volume_type']);
updMpdConf();
sysCmd('systemctl restart mpd');
workerLog('worker: MPD config: updated');
I ran a quick test on a Pi that has a USB DAC and no issues after unplugging it and restarting. Audio was reconfigured to HDMI 1.
In order to debug your specific issue I would need to be able to reproduce it on my end.
Right. pgrep worker.php returned nothing (Putty SSH). Also correct that the D30 DAC was off during this startup. I understand that debugging is difficult without reproduction. Any other logs that I could provide perhaps? Did you attempt setting up a simple filter and config in CamillaDSP using my initially provided .wav IR file?
