Hi All, |
| 2 |
|
| 3 |
My sound has been behaving erratically for a while now, probably since |
| 4 |
pulseaudio started being shipped with various desktop applications. This is |
| 5 |
what I am talking about: |
| 6 |
|
| 7 |
Sound level undesirable |
| 8 |
============== |
| 9 |
Kmail pops up a warning and the sound level is 100%. The first time. On the |
| 10 |
second warning when it happens a couple of seconds later, the sound level is |
| 11 |
back down to normal levels, say 55%. Without me interfering with any audio |
| 12 |
settings. |
| 13 |
|
| 14 |
Some time later another warning pops up and this time the sound may be normal, |
| 15 |
a second warning a couple of seconds later may be back to 100%. It appears to |
| 16 |
me as if sound levels generated by dekstop/application warnings are adjusted |
| 17 |
dynamically on the fly and at will, but not my will ... |
| 18 |
|
| 19 |
Non-KDE applications, e.g. Pidgin bleep at top volume when IMs are |
| 20 |
sent/received. Adjusting their volume thankfully sticks, at least for the |
| 21 |
desktop session in question. |
| 22 |
|
| 23 |
|
| 24 |
Alsamixer |
| 25 |
====== |
| 26 |
Running alsamixer shows: |
| 27 |
|
| 28 |
Card: PulseAudio |
| 29 |
Chip: PulseAudio |
| 30 |
|
| 31 |
with a single Master bar for adjusting the volume. Selecting F6 shows Sound |
| 32 |
Card set to (default), with 'HDA Intel MID' and 'HDA ATI HDMI' below it. When |
| 33 |
I select 0 for 'HDA Intel MID' I get all my familiar alsamixer settings back |
| 34 |
including Master, Headphones, Speaker, PCM, Mic, etc. |
| 35 |
|
| 36 |
Adjusting these allow me to arrive at sane volume levels as used to be the |
| 37 |
case in the past. However, the annoying thing is these settings do not stick |
| 38 |
between reboots. |
| 39 |
|
| 40 |
|
| 41 |
On another laptop with a different audio card, things are even stranger. The |
| 42 |
card pops/crackles at boot time, but all sound is dead unless and until I run |
| 43 |
alsactl init. Then if the sound gets quite loud, e.g. the other side of a |
| 44 |
Skype call raises their voice above a certain level, all sound is lost until I |
| 45 |
run alsactl init again. This is becoming tedious to say the least. |
| 46 |
|
| 47 |
|
| 48 |
Have you noticed anything similar to either of the above problems ? What may |
| 49 |
be causing these problems and are there any fixes/workarounds? I honestly |
| 50 |
can't recall sound ever being such a pain on my systems. |
