Sorry for my long silence.
I’ve tried the things, which ardour suggested me.
I’ve increased the amount of locked memory from 64 kB to 2048 kB with command ulimit -l. - No effect. On the second track the same old problem.
I’ve tried to change power and performance settings, but they already on highest level. (I don’t have as much experience with Linux, as I want, but through GUI all set on highest performance). Maybe this was a standard ardour advice for notebooks. So, the performance settings does not changed situation at all.
At last, I’ve decreased Audio to buffer to 10 milliseconds, and latency correction to -10. Everything is working! and 10, 0 also works.
If I use buffer 100 milliseconds and latency correction -100 and -90, I have periodical lost in sound, like before.
The situation is quite strange for me: if I use the big Audio to buffer value, everything works. If I use small value - everything works. If I use near-default value, sound is periodically lost.
As I understand, the recorded audio going into buffer in RAM, the amount of sound in buffer declared by preferences (10 milliseconds, for example) and then, with latency correction it goes to hard disk and Audacity. Am I right?
So what will load system more? the big buffer or small? Can you tell me the pros and cons of big (300 ms) and small (10 ms) audio to buffer values?
Also, I’ve tried to start Audacity through terminal (I know, I have to do this earlier, but GUI is so beautiful
)
I have such errors:

But audacity starts and everything is working.
as I understand this is an old error in Suse, and it have no solution to this moment.
