Jelentem kollégák, hogy sikeresen orvosoltam a problémát.
Igaz, hogy a 9.04-re frissítettem rá a 9.10-et. ugyan megkérdezte, hogy cserélje-e le a default-pa-t de mondtam neki, hogy hagyja csak meg szépen.
a köv leírással sikeresen kreáltam egy mic boostot:
1) create/update your /etc/asound.conf:
# creates a new alsaboost device that takes over sound card
pcm.alsaboost {
type asym
playback.pcm {
type hw
card 0
}
#software gain upto 50dB for digital microphone
capture.pcm {
type softvol
slave.pcm "hw:0,0"
control {
name "+50dB Mic Capture Volume"
card 0
}
max_dB 50.0
}
}
ctl.alsaboost {
type hw
card 0
}
----
2) modify your /etc/pulse/default.pa, in order to add the two uncommented lines below at a
similar place in your default.pa (around line 35 in my case), and keeping all the
remaining lines in your default.pa (this location is important, do not put them at the bottom
of default.pa or otherwise alsaboost will not load properly in pulseaudio because it
will prefer to load, instead, the original sound device via module-hal-detect a few lines down):
### Load audio drivers statically (it's probably better to not load
### these drivers manually, but instead use module-hal-detect --
### see below -- for doing this automatically)
#load-module module-alsa-sink
#load-module module-alsa-source device=hw:1,0
load-module module-alsa-source device=alsaboost source_name=alsaboost_source
load-module module-alsa-sink device=alsaboost sink_name=alsaboost_sink
#load-module module-oss device="/dev/dsp" sink_name=output source_name=input
#load-module module-oss-mmap device="/dev/dsp" sink_name=output source_name=inp$
#load-module module-null-sink
#load-module module-pipe-sink
2b) in case you have several devices, or for some other reason alsaboost doesn't become the default source/sink in pulseaudio, you can force that by adding the following two lines at the bottom of default.pa:
set-default-sink alsaboost_sink
set-default-source alsaboost_source
3, comment out the line 'load-module module-hal-detect' in your /etc/pulse/default.pa (just add a # in front of it).
Szóval sikeresen megoldódott a probléma. (azt még azért megkéredm, hogy ha új telepítést csináltam volna a karmicból és utána végeztem volna a módosításokat, akkor is működne?)
