<pre>I have Mageia 4 x86_64 with all updates installed, so kernel 3.14.24.
On a Dell Inspiron 7720 17R SE laptop.
Both with speakers as with Logitech H800 wireless headphones via Bluetooth, I
have an interruption of sound during 380 milliseconds exactly every 20 minutes.
This is proven by journalctl:
Dec 02 21:12:03 Dell7720Mageia4 pulseaudio[2969]: [bluetooth]
module-bluez5-device.c: Skipping 387514 us (= 68356 bytes) in audio stream
Dec 02 21:32:04 Dell7720Mageia4 pulseaudio[2969]: [bluetooth]
module-bluez5-device.c: Skipping 387286 us (= 68316 bytes) in audio stream
Dec 03 21:08:58 Dell7720Mageia4 pulseaudio[2791]: [bluetooth]
module-bluez5-device.c: Skipping 386450 us (= 68168 bytes) in audio stream
Dec 03 21:28:58 Dell7720Mageia4 pulseaudio[2791]: [bluetooth]
module-bluez5-device.c: Skipping 391516 us (= 69060 bytes) in audio stream
How can I debug this further to find a root-cause?
I did the following, at 19 minutes 50 seconds I ran:
top -bd .1 -n 150 > top_log_3.txt
grep -A 2 COMMAND top_log_3.txt > top_log_3_grep.txt
This resulted in just at the moment of sound interrupt (2 experiments with same
result):
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
601 root -51 0 0 0 0 S 9 0.0 0:03.39 irq/46-iwlwifi

But what can I conlude from this?</pre>
