Summary: A flavour of Intel HD audio not implemented?
Product: Drivers
Version: 2.5
KernelVersion: 2.6.27.7 (or 2.6.28.1)
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Sound(ALSA)
AssignedTo: perex at perex.cz
ReportedBy: thoralf.dassler at gmail.com
Latest working kernel version: probably none
Earliest failing kernel version: unknown
Distribution: Slackware 12.2, mainline kernel
Hardware Environment: Toshiba Satellite L300-1AQ
Software Environment: KDE-3.9.10
Problem Description: Sound works, volume change too, but:
1) There is only the Master slider in alsamixer after reboot; once KDE is up, I
manage to get two sliders: Master and PCM. This means many channels
are not available -- among them the microphone, which I need
2) Plugging in external speakers or headphones: laptop speakers do not
disengage
3) None of the available snd-hada-intel implementations in the kernel affect
the situation
