Brief history of the landing to Rosa is linked to my sound problems.
I am new to Rosa (I have checked it from time to time, but never installed and used is regularly), but not new in linux. This summer I have got a new laptop, a LENOVO IdeaPad Slim 5 15ARP10, AMD Ryzen 7 7735HS, with no OS. I have tried more than 20 linux distibution, of different kind and base, from the most well known ones to obscure ones, up-to-date ones – but I had troubles with the sound in speakers – the headphones were OK. The most distros had no sound in speakers trying the live iso. The last try was Rosa Fresh 13 – KDE version. Also no sound in speakers. But during my trial on the live iso, when a video were playing (no sound from the built-in speakers), I was interrupted in my work and closed the lid of the laptop. The laptop went to sleep mode. When I turned back and opened the lid, the sound was working.
After this experience I retested the other distros, and happened the same – after waking up from sleep, the sound was working. I decided to install one of the two distros (only 2 from 20!) which had sound without going first to sleep. But after installation I had no sound again. I did not found any solution on internet for my problem, having sound only after wake-up.
I was in doubts what to do after this experience. Because I had the luck with Rosa to discover a way to make the sound working, also because it looked polished, snappy, and using the smallest amount of RAM from those 20 distros, I decided to install it. No sound in speakers after installation. I made a complete update, without any issue, and after that, BIG and GOOD SURPRISE, the sound in speakers began to work. So a BIG LIKE for Rosa. Something from the updates helped. I decided to stay with Rosa.
And here is the biggest problem I have, with the microphone, to which I have not found a solution. I suspect that the source of the problem might be kernel-related. I am running the latest 6.12.34 kernel available in Rosa’s repository.
I installed, personalized and tweaked everything I needed (it was a big work, few weeks). At the end of it, more than a week ago, I discovered that the built-in microphone is not working. I did not checked this right after installation, but it does not appear in volume plasmoid, and is grayed out in the plasma sound settings. I cannot record anything. I have tested all possible combinations which gaved me audacity. The default settings functions like a monitor (if a sound is played on the computer, that is recorded directly by audacity, not thru the microphone). But if I use a headphone with microphone, with the default settings, everything is working OK, the headphone’s microphone appears in the volume settings and plasmoid too.
But I need the built-in ones to work.
Then, I retested the most representative ones from those 20 distros, and all has the same problem, no microphone (the sleep does not help getting microphone to work). Actually, I have downloaded yesterday two new snapshots of some rolling ones, and now the built-in microphones works on one of them. So, now is confirmed, that it is not a hardware problem. Also, I don’t want to reinstall everything, just stay with Rosa, I hope I can, at least for the next 5 years minimum, but I am hoping for more.
Sorry for the long writing. I hope the info help others too. In the next post I will be shorter.

Thank You for Your work and help!
