Dear Sylvia,
Thank you so much for your kind cooperation!!
As discussed and I have gone through some of the videos for optimal audio production using laptop for win-8.1, as per the recommendation , i updated bios, chip-set and followed battery optimization and disable nvidia, usb power management.. etc..,
1) From the day one i got some craky sound from next to the touch pad location ( where the hard disk is locating) and little heat..
2) Apart from that, i did all updates and checked the audio... there is no improvement
3) By trial and error i made an attempt to connect different plugs ( playback, recording device in sound settings)
4) At last, i found the line in which is in the tab playback ( speaker and microphone)
5) I did some experiment of audio settings,
in the playback device from the sounds settings,microphone ( line in ) as 100% , enhancement - disable all effects
24 bit 48000 studio quality
6) recording devices: microphone / disable all & stereo mix / un tick the listen category/ level as 100%, enhancement - disable all sound effect, 2 channel 16 bit DVD quality
7) with this settings, i can able to do windows on board recording and perform live music in chat rooms, with line in facilities i cant enhance the volume level and mic boost
8) When i activate the realtek recording tab i am getting latency/ de accelerate the timing ( double voice, pulling down the performance, de-accelerating)
9) I am suspecting that the motherboard will have the problem interconnecting with realtek on board sound card ( I updated the driver as recommended by HP)
11) I didn't try the link https://www.youtube.com/watch?v=PhQVkv3NM3k
12) ref point 1 , i went to the HP service center and ask them to check the craky sound , they said the sound is from hard disk and they will replace.
I asked them to add additional ram to increase the cache memory and also to check the echo effect ( latency)
13) The laptop is with HP service center now,
14) Earlier i bought 3 number of different 3.5mm stereo/mic adapter pin converter ( 4 step pin) to interconnect my old headphones with mic
nothing is working. have you found any solution and also realtek latency issue and how about usb audio splitter? have to check M-Audio
Thanks & Regards
