hdaudio defaults on T61p

Postby hopet » Mon Jan 21, 2008 2:58 pm

Hi,

I wonder whether it's caused by default mixer settings in OSS, but after installing lates OSS port 4.0.b1012_3 on FreeBSD 7.0-RC1 (while switching from default sound and snd_hda modules), I've got an awful sound feedback between the internal mic of Lenovo T61p and it's speakers. This may fairly easy to turn off once you find out where it is, but it's definitely scaring for normal users.

It is probably just due to mixer settings as unlike Alsa where all channels are initially muted Oss driver levels are set to 80% max. & vmix's levels to 100%.

Mixer settings can be saved by the superuser with the savemixer command and should be automatically saved at shutdown.

Yes - maybe time to change those defaults, at least for routing the mic directly into the speakers. This is annoying feature for most of the apps anyway (except when you really need it for some testing, but then I'd say it's up to the application/user to turn this feedback on).

Btw, I've noted there might be some problem also with the driver as it says

hdaudio0: [ITHREAD]
hdaudio: Too many connectionsi(B) for widget 29 (24)
hdaudio: Unknown HDA codec 0x14f12bfa
hdaudio0: <Intel> mem 0xfe220000-0xfe223fff irq 17 at device 27.0 on pci0

on load.

Thanks,
Petr

The unknown HDA codec 0x14f12bfa refers to your Conexant Soft Data Fax Modem. Not sure about the other warnings though.
