Make sure, that the user which starts jackd is allowed
to raise the real
time priority and memlock address space.
...
In this case, the user has to be in the @jackuser group to be able to
raise the priority.
Thanks, I thought it would something like that, Ok I'll have to figure out how to do
it on Raspbian.
What error message do you get without sudo? Maybe your
user has to be in
the "audio" group (or similar).
The error is:
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
aplay: main:788: audio open error: No such file or directory
And the "pi" user seems to be in audio group:
groups
pi adm dialout cdrom sudo audio video plugdev games users input netdev gpio i2c
spi
Running with sudo plays audio just fine.
