Re: Jack server is not running and cannot be started

(I) I'm not shure, if you check wether the alsa tools are installed. Enter alsa <TAb twice> not Enter, you should get $ alsa alsa alsactl alsaloop alsamixer alsaucm A second way to check: dpkg -l alsa* (II)To you get an sound, if you enter sudo aplay /usr/share/sounds/alsa/Front_Center.wav ?

Da es bei diesem Artikel keine Beschreibung gibt, welcher Chipsatz verbaut wurde (und ob es immer der gleiche ist), ist es aus meiner Sicht ein Glücksspiel, ob dieser Adapter wirklich im Raspberry funktioniert.

Re: Jack server is not running and cannot be started

adding 2>/dev/null (without spaces!) to the end of the espeak command only supresses the error messages, there will be sent to the device /dev/null. This is cleaning the output. The other commands suggested and their output/ results could help to find out the possible causes. If you will go ahead, y...

Hi ghans,
what error messages to you get, when you try to execute espeak? Is it working for you?
On my Pi espeak produces sound, and i get the messages too, so I see no need for jack working

Hi Simon, you have to stress your Pi, e.g. with time echo "scale=5000;4*a(1)" | bc -l && cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq The output from cat /proc/cpuinfo delivers only an static value.

Re: Jack server is not running and cannot be started

Installed alsa packages can be controlled with

Code: Select all

dpkg -l |grep alsa
The command

Code: Select all

lsmod
should give you also a line bgeinning with

Code: Select all

snd_bcm2835 
and many other lines beginning with snd. These are the drivers needed for sound.

Re: Jack server is not running and cannot be started

after installing the alsa software, you should reset alsa by

Code: Select all

alsactl  init
This informs you about the sound hardware found.

Do you have installed the alsa package (type 'alsa' and the tab key twice, you should see some commands beginning with alsa..)? If it isn't installed, do that with sudo apt-get install alsa-tools alsa-utils After installing, you can set the output volume through alsamixer Try this with sudo aplay /u...

Re: SD card end of life?

Maybe your integrated card reader in your notebook isn't supporting SDHC cards, like yours.
Older readers can only read (and write) the older sd cards, limited to 2 GB.
Do you have an external card reader, or can buy one?

Re: Jack server is not running and cannot be started

Hi Matthew,
As you can see, 'meistervision' did get these messages although. I got this errors too. A workaround is to add

Code: Select all

 2>/dev/null
at the end of the command line, e.g.

Code: Select all

espeak "Hello, I am Espeak, the voice synthesizer" 2>/dev/null 
Does this work for you?
