To, The Team Debian-User, debian-user@lists.debian.org, Debian.org My dear illustrious Team Leaders,
Good morning. Model (India): Lenovo IdeaPad 320-15ISK 80XH01FKIN 15.6-inch Laptop (6th Gen Core i3-6006U/4GB/2TB/Integrated Graphics), Platinum Grey The OSes are Debian (Stretch) 9.11.0 Lxde and Knoppix 8.6.0, in 64-bit operation. All details/specifications of my used Lenovo laptop are also in the Debian Forums post (to avoid clutter and maintain centralised notes). http://forums.debian.net/viewtopic.php?f=7&t=146606&p=722991 I am searching for Realtek audio drivers for Linux for the Hardware details: "Lenovo ideapad 320-15ISK" LNVNB161216, and "Realtek Audio_6.0.1.8652.A.",otherwise, I am afraid that the audio won't be be to operate in duplex mode, i.e., won't record audio while playing it. I have posted the topic in Debian Forum here: http://forums.debian.net/viewtopic.php?f=7&t=149074, but as said earlier too, it is difficult to find solution in the Debian forum. I assure you that, as always, I shall post a [Solved] reply in the Debian Forums at the end of this experience for future users. Regards, Rajib Bandopadhyay A dedicated Debian and Knoppix user
