Stereo Tool

Hi all,

Spent about 3 hours tonight trying to get ST working on either raspberry pi 2 or 3 - using the Cirrus Logic Audio Card.. no luck at all.

I've installed jackd2 followed the command line instructions to start jack server and the ST GUI fails to find jack running on the Pi.

I'm looking to just process line in to line out on the card at the moment.

Have tried with raspian wheezy and Jessie, have had card showing up in both versions so I know driver is installed, it just seems ST is not picking up the card from Jack.

Any help would be appreciated, if someone has an image they would share I would be very very grateful.

Cheers.

Hello

I just after few hour with ST 8.0 installation at RPI 3 with wolfson audio card and it more of less working

(first few steps to other people who want to try with ST @ RPI)
- i started with latest RASPBIAN JESSIE from RPI website
- unfortunetly wolfson card not working - problem with kernel(?)
- go to this website http://www.horus.com/~hias/cirrus-driver.html
compile or use kernel cirrus-linux-4.4.14.tgz
i use ready becouse of lack of time but maybe i can try compile next time

if ather this you see

pi@raspberrypi:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpiwsp [snd_rpi_wsp], device 0: WM5102 AiFi wm5102-aif1-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0

success !

before you want to listen/record using card you need to start commands depending what you need to do with card

./Playback_to_Headset.sh
./Playback_to_Lineout.sh
./Playback_to_Speakers.sh
./SPDIF_playback.sh
./SPDIF_record.sh

......

(in pi/home/bin)

next setting jackd to work with high priority
dpkg-reconfigure -p high jackd
after this start jackd

sudo jackd -d alsa -p 4096 -n 4 -r192000

192000 becouse i want to use stereo encoder out
without sudo it can't allocate extra memory for jackd


after this

i starting in termianal ST (to see debug messages)

sudo ./tereo_tool_pi2_gui 

after all this things i can set inputs and output in ST.
the problem is with buffer ST play but every few second stops .. and play again.

where to download old version of ST for RPI ?

Chances are that the CPU load is too high. Try turning some things off, and lowering the Quality slider. The next version of Stereo Tool will probably work much better (since it can use more cores).
