Sound Stops Working After Playing Sound in LMMS

Having trouble with LMMS? Ask about it here.
I have a Lenovo ThinkPad T410 running Linux Mint 19 64 bit. Sound works just fine until I play a sound in LMMS. Sound does not resume working until putting the laptop to sleep and waking it up (closing and reopening the laptop). I don't know why this is happening. If you guys have any ideas on how to troubleshoot this issue, please let me know. I am a newbie when it comes to Linux in general. Thanks.
Are you using the latest version of LMMS ?

'play a sound' .. As in
1) ONE specific sampled sound ?
OR
2) ANY sound at all ?
including ANY instrument ao sample?

I believe you have a NaN event. where one wave is kept as a 'standing wave', oscillating in extreme low frequency. That will block the output for maby ..hours(!)
But answer the questions above, and we can get to the bottom with this..

Besides that, since you are new in Forum
