Nexus One Speaker/microphone problem

Hi,
i've got a nexus one and I installed the MoDaCo custom rom on it. Everything was fine even last evening. This morning however, my speaker didn't work anymore and also the mic isn't working. When I try to do the speech thing it shows me a mic with a red bar accross, like there is no mic connected. Could this be a problem related to the custom rom or is this just a hardware failure?
What should I do? If i ship it to HTC it'll be 3 weeks until I get it back.
nandroid back to your stock rom?
It still worked while on the MoDaCo custom rom and I did a nandroid restore which didn't help

Earpiece is not working

1. After installing custom ROM (Pixel Experience 8.1), I have noticed my earpiece (receiver) isn't working. Yesterday I tried clean flash older Lineage OS 14.1 but earpiece still not worked after that. Maybe some problem caused this while installing these ROMs, but I did clean flash (wiped dalvik/cache/data) each ROM. So I decided to try installing stock ROM, I did this with TOOL_ZUK_Z1.
I'm now back in stock firmware and stock recovery too but this not solved my earpiece. still no sound from it. I tested it with app called: "Phone Doctor Plus" and in the results only lowest frequency 300mhz (2000/8000/12000Mhz don't work) but there is still no sound I'm able to hear physically. So is there any options to try to make it work? Or maybe is hardware issue this time?
2. I still have 1 year warranty, so my second question is: will be there no problem sending it to warranty center.... when I went back to stock ROM (cm-12.1-YOG4PAS7DF) and stock Cyanogen recovery?
Sorry for my amateur level english.

Would recommend to claim warranty. Flash stock rom, stock recovery and lock bootloader. You can use the tool for that.
Zuk Z1's main speaker is giving a low output sound.Please help me to solve this issue.
