Hi Everyone,
OP here, I came back, because of job related events made me jumped out of this issue and I was using old kernel anyway . But I came back because of a new install , I am facing it again.
And then I saw what happened in between.
Congratulations AlbertoZ and sorry for not coming back to you when you asked. I was stuck at how to contact alsa dev, I am a dev myself (simple web app though) and my apps got the best of me regarding this problem I simply dropped it but boy oh boy, if there is a fix now I will happily use the latest kernel.
I really came back here without much hope, I was wrong, you are a boss, thank you and everyone that put time and efforts in this thread.
I will stick around if need be but I am so glad you guys are great.
One love.
edit : we gotta love this vs-100, still my main everyday sound card
