[Ardour-Users] Install of upstream jackd 1.9.10: unknown driver alsa

[jonetsu at teksavvy.com]

So I tried to replace the current jackd provided by Linux Mint as the
export problems with Ardour are getting ridiculous.  Even a short audio
clip will not export.  I mean, a second short audio clip, as a first
one was exported nicely.  First one works, second one 1 minute later
does not.

Note that I am calling jackd in the exact same way it was done by the
Linux Mint installation.

The new jackd does not find the alsa driver.  Why ?

Here are the steps to replace jackd.  The script file as well as waf
install output are available.

1) save some data

Saved the current calling of jackd as per the Linux Mint system, from
the ps aux output, which is:

/usr/bin/jackd -T -ndefault -t 200 -p 2048 -R -T -d alsa -n 2 
-r 44100 -p 1024 -d hw:M1010LT,0 -X raw

2) remove and install

Got the output of dpkg -L jackd and removed all listed files by saving
the output, removing the directory names only, and adding 'rm' in
front of each line.  The resulting script is called removeJack.

The waf configure and build were already done.

(as root)

killall jackd

./removeJack

./waf install

[snip]
waf: Leaving directory `/Share/src/Audio/jack-1.9.10/build'
'install' finished successfully (0.624s)

which jackd 
/usr/local/bin/jackd

ldconfig

3) start the new jackd

/usr/local/bin/jackd -T -ndefault -t 200 -p 2048 -R -T -d alsa -n 2
-r 44100 -p 1024 -d hw:M1010LT,0 -X raw
