Guitar connection to ACER

hu flag

my Acer laptop only has one 3.5 jack. When trying to connect to it as a line input, a number of problems arose. The laptop offers to define the equipment as either a headset or headphones, but not as a line-in. When an external sound card is connected, it becomes possible to select the input as a line input, but the problem of connecting the guitar to a laptop remains: when rakarrack and QJack are connected, the ability to watch video disappears, and rakarrack itself stubbornly takes the sound from the microphone at all switching options. there is no line input in the switching screen switching Help me set up the connection, please. OS - Ubuntu 22.04

Welcome to AskUbuntu. An electric guitar doesn't work as an active microphone. You need a direct box, likewise a clever system. If the 3.5 Jack is combo on the Acer laptop, the Ubuntu recognizes it as a duplex out/input in one condition; you use a TRRS 4-segment plug.

@SadaharuWakisaka, Thank you for your answer. This input correctly work on my laptop when I run windows so I think ubuntu can work with it too without any additional hardware. But I don't know how to set everything up

`PulseAudioVolumeControl` is a candidate to make it happen. `sudo apt install pavucontrol` if you will.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
