Hi all, just for the record:
I also had this issue for the first time ever.
No audio on phone calls.
On incoming calls, I heard it ring, but then silence.
After a single power-cycle of the phone, it worked again.
OS: Koli 4.0.1.
Phone: XA2 Dual-Sim
In the journal I find:
Feb 20 09:23:29 XperiaXA2-DualSIM kernel: qdsp_cvp_callback: cmd = 0x13198 returned error = 0x1
Feb 20 09:23:29 XperiaXA2-DualSIM kernel: voice_send_cvp_topology_commit_cmd: DSP returned error[ADSP_EFAILED]
