Or if it can't work for you, ask your distro people who can help. And, I'm afraid that it's not the sound subsystem but the DRM graphics driver that actually broke. In that case, you're reporting to a wrong list, and further ping wouldn't help. (And for figuring it out, you'd need the bisection, so going back to square...) thanks, Takashi > --- > > Gilberto Nunes Ferreira > > > > > > --- > > > Gilberto Nunes Ferreira > +55 (47) 99676-7530 - Whatsapp / Telegram > > > > > > > Em qui., 5 de mar. de 2026 ās 10:06, Takashi Iwai escreveu: > > > > On Thu, 05 Mar 2026 13:54:45 +0100, > > Gilberto Ferreira wrote: > > > > > > Hi there... > > > > > > I just installed ArchLinux, because I thought that perhaps > > > Ubuntu/Debian was the culprit. > > > So, I went ahead and installed linux-mainline from AUR. > > > But I get this same result. > > > > Then please try to git bisect.
