Subject: snd-powermac @ G4 DA (PowerMac3, 4) - headphone detection doesn't work
Date: Tue, 23 Feb 2010 17:20:58 +0100 [thread overview]
Message-ID: <29bea45b1002230820m5111e0cu6006e6636201049e@mail.gmail.com> (raw)
I can hear sound with internal speakers only if I plug headphones
jack, without plugged jack, there's no sound at all; to listen thru
headphones, I need to half-insert that jack and this leads to
distortions; with h/phones jack plugged fully, no sound in phones, but
sound in internal speaker. With the same half-plug, in OS X I head
sound both via h/phones and internal speaker.
Driver: snd-powermac. Audio card: Tumbler @ i2ca @ KeyLargo i2c (I can
provide the full dump of OpenFirmware device tree).
As <gnubien> at #alsa @ irc.freenode.net suggested, I ran `alsamixer
-c 0` and MM-ed 'Auto Mute'. After that, I can fully plug h/phones
jack and enjoy full sounds w/o distortions but still can't get any
sound when it's unplugged.
The result of running ./alsa-info.sh:
