K3--complete audio loss when rig is turned on

K9IR
I am experiencing total audio loss--both through headphones and the speaker, and across all modes and bands--shortly after I first power up my K3. If I power cycle the K3, audio returns but then often vanishes again shortly thereafter. After "enough" power cycles, the audio will remain so I can use the rig without issue.

I can tune with the VFO knob and change modes, so the radio is not totally locking up.

On occasion--but increasingly less so--I will see an E[rror] numeric message on the display and a reference to the DSE. However, most times the audio just vanishes while the display continues to show the frequency.

After the rig has been on for "a while," the issue goes away until the next time I go through a "cold start," so it may be something temp/time related.

In researching this list, I've seen the references to reloading the firmware. I have tried that once to no avail.

I have the following firmware versions loaded:
MCU 04.39
FPF 01.14
DSP1 02.73
DSP2 02.73
K3 utility 1.4.4.25

I also am using a P3 loaded with firmware version 01.09.

Does anyone have ideas on what could be causing this or what else I could check/test/tryto resolve this issue? Many thanks for any insights.
