I have the same problem on Acer Ferrari One 200 running ubuntu 10.10 x86_64.
But, the mic is working flawlessly when I run live-usb 10.10 i386 (32 bit). So, I guess there is a problem with the 64 bit version, either the alsa or pulseaudio (I am not sure). I won't switch to 32 bit kernel, since I won't get the optimal power of my machine. And I hope that there is somebody can fix this problem. @Luke: there is no "acer" model in ALC272 section. Here is the available model: ALC662/663/272 ============== 3stack-dig 3-stack (2-channel) with SPDIF 3stack-6ch 3-stack (6-channel) 3stack-6ch-dig 3-stack (6-channel) with SPDIF 6stack-dig 6-stack with SPDIF lenovo-101e Lenovo laptop eeepc-p701 ASUS Eeepc P701 eeepc-ep20 ASUS Eeepc EP20 ecs ECS/Foxconn mobo m51va ASUS M51VA g71v ASUS G71V h13 ASUS H13 g50v ASUS G50V asus-mode1 ASUS asus-mode2 ASUS asus-mode3 ASUS asus-mode4 ASUS asus-mode5 ASUS asus-mode6 ASUS dell Dell with ALC272 dell-zm1 Dell ZM1 with ALC272 samsung-nc10 Samsung NC10 mini notebook auto auto-config reading BIOS (default) Please let me know if somebody need more informations. -- [Realtek ALC272X] Recording problem https://bugs.launchpad.net/bugs/653266 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
