|Reproducibility||have not tried|
|Fixed in Version|
|Summary||0008275: 'blips' of input signal appear at output when locating|
|Description||Using 'P' to locate the playhead allows a brief blip of the channel input signal to pass through, even when ardour is set to 'record monitoring handled by audio hardware'.|
|Steps To Reproduce||* set 'Record monitoring handled by:' to 'audio hardware'|
* create a new session
* add 1 mono track, routed to master bus
* connect hardware input 1 to audio track
* record a region on the track (to create start & end markers)
* delete the region
* feed a signal into the hardware input
* locate the playhead to different points in the session by pointing with the mouse and pressing 'P'
* on every locate a short 'blip' of the input signal can be heard from the output of the master bus
|Additional Information||With jackd1 from debian stable, using a Delta 1010:|
colinf@starling-thinkstation:~$ jackd --version
jackd version 0.125.0rc1 tmpdir /dev/shm protocol 25
Maybe not relevant, but zita-a2j, zita-j2a, and a2jmidid were also running via qjackctl's 'Execute script after Startup:':
zita-a2j -dhw:M44 -c4 -jdelta44 & a2jmidid -e &

Is "Session > Properties > Monitoring > Track Input Monitoring automatically follows transport state ("auto-input")" enabled?
and Preferences > Signal Fow > Auto Input does 'talkback' ?
"Auto Input" is on
"Auto Input does 'talkback'" is off
"Session > Properties > Monitoring > Track Input Monitoring automatically follows transport state ("auto-input")" is on
||Have reproduced with ALSA backend too. 'Auto Input' doesn't make any difference.|
Issue was found and understood just now..
It is possible that Route::monitoring_state() returns (MonitoringDisk | MonitorSilence).
However when locating the disk-reader only silences the buffer if (ms == MonitoringDisk).
I have a fix for this in the queue (preventing monitoring_state to become Disk|Silence), but the 6.1 tag got in the way.
||I've checked, and can confirm this is fixed in 06535071. Can also confirm that the issue was introduced (for me, at least) by fbe80751, as you suspected, so it wasn't in 6.0.|
||Fixed in 6.1-1-g308d138144|
