Line-in microphone gives very poor quality voice recording

[PB1957]

Line-in microphone (3.5 mm jack) gives  poor quality voice recording with very low volume [ maximum 4%] and disturbance. Consequently I cannot use it for dictation. Mic is Emkay headset (mono) approved for Dragon voice recognition software. Laptop's built-in microphone functions well.

In the Realtek High Definition audio driver properties, the following message is given in the events log :

Device HDAUDIO\FUNC_01&VEN_10EC&DEV_0295&SUBSYS_103C8216&REV_1000\4&34719e6e&0&0001 requires further installation.

The audio driver details are as  under:

driver provider: Realtek Semiconductor

driver date : 20.12.16

driver ver: 6.0.1.8023

Please guide. Thanks.
