Hi all,
I get no sound. After reinstalling Stretch a couple of months ago, the
computer is silent. Well, not completely, because these warning beeps at
end of line etc.. are coming out. Normally I have all those disabled,
but for testing this is established, so I am quite sure the audio card
is OK.
The computer is a Hewlett Packard laptop model HP Pavilion dv4-1199eo.
Inxi -A presents this information:
Audio: Card Intel 82801I (ICH9 Family) HD Audio Controller
driver: snd_hda_intel
Sound: Advanced Linux Sound Architecture v: k4.9.0-6-amd64
After a reboot I can find among other things this information in
/var/log/syslog:
systemd[1]: Starting Save/Restore Sound Card State...
and
kernel: [ 14.190720] input: PC Speaker as
/devices/platform/pcspkr/input/input18
kernel: [ 14.201142] input: HDA Digital PCBeep as
/devices/pci0000:00/0000:00:1b.0/sound/card0/input14
kernel: [ 14.206632] input: HDA Intel Dock Mic as
/devices/pci0000:00/0000:00:1b.0/sound/card0/input15

/devices/pci0000:00/0000:00:1b.0/sound/card0/input16
kernel: [ 14.206817] input: HDA Intel Front Headphone as
/devices/pci0000:00/0000:00:1b.0/sound/card0/input17
so I think I can feel assured the system has contact with the audio card.
I have removed two fields before each line containing date and computer
name.
After the install of stretch I did remove the Pulsaudio package and
instead installed the Jack package, this recommended by the Ardour team.
Ardour is a program very important for my use of the computer, so I
really want that program to work fine. I have done this measure before
in the jessie era, so I know it works. Trying to make a connection in
the QjackCtl program fails, and I can read the following message. Line 3
and 11 is partly in Swedish, meaning that the file or directory does not
exist, but no information is given about which file or which directory,
so I feel a bit lost:
23:16:56.103 Statistics reset.

Since I am not very skilled in the sound technology I have previously,
when I carried out this operation, randomly installed every package I
found, which seemed to deal with sound until it all worked, but this
time my intention is to do the job in a more deliberate way.
So is there anyone who can give hints about what I have missed so far?
