Min trådløse mikrofon virker ikke, så jeg skriver svaret i chatten.

Because mikrofon is a common gender noun in Danish, not a neuter noun.

• en mikrofon = a microphone
• therefore: min mikrofon = my microphone

Danish possessives change with the gender/number of the noun:

• min for en-words
• mit for et-words
• mine for plural

So:

• min mikrofon
• mit svar
• mine bøger

In this sentence, mikrofon is singular and common gender, so min is correct.

This is because the adjective comes after a possessive word like min.

In Danish, adjectives often take the -e form when they are used in a definite-like context, including after:

• min / mit / mine
• din / dit / dine
• den / det / de
• names in possessive use, etc.

So:

• en trådløs mikrofon = a wireless microphone
• min trådløse mikrofon = my wireless microphone

This -e ending does not mean plural here. It is just the form Danish uses after min.

Here, virker means works or is working.

The verb at virke can mean several things depending on context, such as:

• to work / function
• to seem / appear
• to have an effect

In this sentence:

• Min trådløse mikrofon virker ikke
  = My wireless microphone isn’t working

So here it clearly means to function.

Because in a normal main clause, Danish negation ikke usually comes after the finite verb.

So the pattern is often:

• subject + verb + ikke

Examples:

• Jeg forstår ikke. = I do not understand.
• Han kommer ikke. = He is not coming.
• Mikrofonen virker ikke. = The microphone is not working.

That is why you get:

• Min trådløse mikrofon virker ikke

and not usually ikke virker in this kind of simple main clause.

Here så means so, as in therefore / as a result.

• Min trådløse mikrofon virker ikke, så jeg skriver svaret i chatten.
• My wireless microphone isn’t working, so I’m writing the answer in the chat.

It is very similar to English so in this use.

Be aware that så can also have other meanings in Danish, depending on context, such as:

• then
• so / such
• part of fixed expressions

But in this sentence, it is a coordinating conjunction meaning so.

Both patterns can exist in Danish, but they do not behave exactly the same way.

In this sentence, så is being used like a coordinating conjunction joining two main clauses:

• Min trådløse mikrofon virker ikke
• så jeg skriver svaret i chatten

With coordinating conjunctions, the second clause usually keeps normal main-clause order:

• subject + verb
• jeg skriver

So så jeg skriver is completely natural.

You may also see så skriver jeg, but that can feel more like then I write / then I’ll write, where så behaves more like an adverb placed first in the clause, triggering inversion.

So for this sentence, så jeg skriver is the expected choice.

Because svaret is the definite form of svar.

• et svar = an answer
• svaret = the answer

Danish often uses the definite form where English also says the answer. In this sentence, it refers to a specific answer the speaker is giving.

So:

• jeg skriver svaret i chatten = I am writing the answer in the chat

If you said jeg skriver et svar, that would mean I am writing an answer, which sounds less specific.

Because svar is a neuter noun:

• et svar = an answer

For many neuter nouns, the singular definite form is made by adding -et:

• et svar → svaret
• et hus → huset
• et bord → bordet

So svaret literally means the answer.

Danish often uses i where English uses in for something like a chat window, text field, group, or conversation space.

• i chatten = in the chat

This is the natural preposition here because the answer is being written inside that communication space.

Prepositions do not always match exactly between English and Danish, so this is a good phrase to learn as a chunk:

• skrive i chatten = write in the chat

The basic form is at skrive = to write.

skriver is the present tense form:

• jeg skriver = I write / I am writing

Danish present tense is often used where English might use either:

• I write
• I am writing

So in this context, jeg skriver svaret i chatten naturally means I’m writing the answer in the chat.

Yes. chatten shows that chat is treated as a common gender noun in Danish.

• en chat = a chat
• chatten = the chat

For many common gender nouns, the definite singular ending is -en:

• en mikrofon → mikrofonen
• en chat → chatten

This contrasts with neuter nouns, which often take -et:

• et svar → svaret

You could say:

• Den trådløse mikrofon virker ikke, så jeg skriver svaret i chatten.
• Mikrofonen virker ikke, så jeg skriver svaret i chatten.

These mean slightly different things from min trådløse mikrofon:

• min trådløse mikrofon = my wireless microphone
• mikrofonen = the microphone
• den trådløse mikrofon = the wireless microphone

So the original sentence emphasizes ownership: it is my microphone that is not working.

Yes, a few common trouble spots are:

• trådløse: the å sound is not like English a. It is closer to a rounded vowel sound.
• mikrofon: stress is typically on the last syllable: mi-kro-fon
• virker: the r affects the vowel quality, and the ending may sound lighter than English speakers expect
• svaret: the -et ending is often not pronounced as a strong full syllable in fast speech
• chatten: since it is a loanword, pronunciation can vary somewhat, but the Danish definite ending -en is important

If you are learning pronunciation, it is best to listen to the whole sentence several times and notice the rhythm:

• Min trådløse mikrofon virker ikke, så jeg skriver svaret i chatten.

Yes, very easily. It has a useful everyday pattern:

• [Something] virker ikke, så jeg [do something else].
• [Something] isn’t working, so I [do something else].

For example:

• Min computer virker ikke, så jeg bruger min telefon.
  = My computer isn’t working, so I’m using my phone.

• Kameraet virker ikke, så jeg tager et billede senere.
  = The camera isn’t working, so I’ll take a picture later.

• Internettet virker ikke, så jeg skriver en sms.
  = The internet isn’t working, so I’m writing a text message.

This makes the sentence a very useful pattern to memorize.
