Given an input, output that input followed by a newline endlessly.
Input will be a string consisting only of printable ASCII characters (0x20-0x7E) and newlines (0x0A).
If input is length 0, endlessly output newlines.
This is code-golf so fewest bytes in each language wins!
yes-newlines but any newlines that could be contained IN the input are instead printed out as \n. kind of depends on how you read the question :D

./script $'Hello\n World' to include real newlines. On TIO you can just add a newline to the command line argument

yes $1 works fine for me

[= also works and is a smiley face; the smile is the only benefit lol.

OP did not specify how the output should happen, said only it has to happen endlessly with a newline after it. AHK was not tailored for cmd interaction. So the output happens repeatedly in a ToolTip at mouse position:
loop
tooltip,%1%`n`n
I like AHK's loop feature. loop repeats the next block forever, loop, 10 would repeat it 10 times. Sometimes I miss this feature in other languages like Python.
The escape character in AutoHotkey is ` (so there are no problems with backslashes in Windows paths). For some reason, a trailing newline is ignored so it is needed twice. (trayTip might not have this "bug" but I cannot test it because running with wine)
loop
msgbox,%1%
I just realized that OP probably wont like this solution, the output happens with user-interaction and includes no newlines. I'll look for another way.
∞┼,
It doesn't work with an empty input because Ohm is bad at input handling compared to other languages, but you can input "".
Explanation
∞ Infinite loop next code (until ";" or end of line)
┼ Get first input
, Println
: # label (unnamed)
p # print the pattern space
b # branch back to the label
Unnamed labels is an undocumented "feature" in sed that works with version 4.2.2, but may not work in future versions.

òÙ
You can't try this online for obvious reasons.
ò 'Recursively
Ù 'Duplicate the current line downwards
V because the output it inside of an nvim session, and isn't printed to STDOUT until it finishes, TIO kills the session and sees nothing on STDOUT. I didn't know about what you said, but unfortunately it doesn't fix V

Code:
x=input " repeat [ label x bk 9 ]
Explanation:
x = input " ; Input Stored in x as String
repeat [ ; Endless Loop
label x ; Print x in Current Position
bk 9 ; Move Back 9 pt
]
Result:
Run with the -n flag.
loop{$><<$_}
Edit: Thanks for @sethrin for the -n flag!
AN/qvo
A
N / q v
o
N/A Push Newline(10) and input onto the stackv redirect into the loopo/q loop that outputs a character and pushes it to the bottom of the stack continuouslyI was going to remove the EOI (-1) indicator from the stack, but it doesn't appear to affect the output any, so have left it saving bytes.
s=input()
while 1:print s
Input is expected to be a Python literal (quotes for a string, square bracket or parentheses with comma-separated items for a list/tuple, etc.)
Python 3 would be +1 byte because print is a function, but also could do raw input without the 4-byte penalty for raw_input() in Python 2.
for(;;)echo"$argn
";
cycle.(++"\n")
Append a newline to the input and make list of infinite copies of it.
Alternative version, also 14 bytes:
unlines.repeat
#
V[R!&@v1+]
-2 bytes thanks to totallyhuman
#\nV[R!&@v1+] Implicit input of string as charcodes
#\n Push charcode of newline
V Create stack2
[R...v1+] While loop, runs endlessly
!&@ Print entire stack1 as chars without popping
f(char*s){puts(s),f(s);}
Basically a recursive function that outputs the string before calling herself again. Its my second post on codegolf so please be nice :p
putStr.cycle.(++"\n")
OpU;ß
Explanation
OpU; output the input with a newline
ß run the code again with the same input
s=>{for(;;)System.Console.WriteLine(s);}
`GDT
Explanation
` % Do...while loop
G % Grab input
D % Display it on a new line
T % Literal TRUE to create an infinite loop
f(char*s){for(;;)puts(s);}
A function, f, that takes a C-style string as a parameter, s. The body of the function loops repeatedly, passing the string to the library function puts, which outputs the string to the standard output (stdout) along with a trailing new-line.
Pretty simple stuff. The only hack here is taking advantage of default-int for the return value and then not actually returning a value. That doesn't matter in this case, though, since the function never returns (it just keeps printing forever)!
f(char*s){puts(s);f(s);} saves a few

x={println it;x(it)}
s->{for(;;System.out.println(s));}
Surprised there wasn't a Java answer yet.
Try it here. (Wait 60 second for it to time-out.)
Real time: 60.008 s according to the Debug-section before it outputs the result (and gives two warnings 60-sec limit exceeded and 128kb exceeded).

Unfortunately I can't remove Q :(
You need to run from command-line like this, so that this is competing:
python3 pyth.py -c "#
"
The interpreter has been fixed too.
i:0(?v
:o71.>~a{
As mentioned in the comments below my first attempt may have misunderstood the question so the newer 16 byte solution has been made, I have left the original below so people may see.
<ov!?+1:i
oa<
while(1){print"$ARGV[0]\n"}
