I have Fujitsu-Siemens Amilo Pi 1505 laptop.
It has on-board audio card Realtek HD Audio.
lspci lists it as
00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)
I have tried Simply Linux, Mageia 1, Debian Squeeze and Linux Mint XFCE. Mageia does not play on this card at all. Others do play, but keyboard combinations Fn-F5 and Fn-F6 to control volume make them stuck. Usually Fn-F5 (increase volume) works OK until Fn-F6 (reduce volume) is pressed. In this case volume comes to zero, then muted and then even manual adjustment on the volume control do not help - it immediately goes down again. But sometimes otherwise - volume control comes up to maximum and nothing can take it down.
What make things worse, when this happens, whole keyboard becomes irresponsible, so I can't look at logs. The only way to fix the situation is power off by hardware button.
At the same time, Windows XP seems to understand Fn-F5 and Fn-F6 correctly.
Did anybody encounter this issue?
Below is extract from dmesg in Mageia, don't know if it helps anyhow.
hda_codec: ALC883: BIOS auto-probing.
autoconfig: line_outs=1 (0x15/0x0/0x0/0x0/0x0)
realtek: No valid SSID, checking pincfg 0x9983013f for NID 0x1d
realtek: Enable default setup for auto mode as fallback
input: HDA Intel Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input7
Other systems have different kernels, for example Mint has kernel version 3.0.
