To run aplay --dump-hw-params I have to compile all the alsa-util 1.0.28 and alsa-lib 1.0.28. I thought it was easier, however missing many dependencies. You know an easier way? or give me a link or address to contact Florian. I wanted you instead show a possibly related issue. If I run the command paplay -v Europa.wav: pi@raspberrypi ~ $ paplay -v Europa.wav Opening a playback stream with sample specification 's16le 2ch 44100Hz' and channel map 'front-left,front-right'. Connection established. Stream successfully created. Buffer metrics: maxlength=4194304, tlength=352800, prebuf=349276, minreq=3528 Using sample spec 's16le 2ch 44100Hz', channel map 'front-left,front-right'. Connected to device alsa_output.platform-snd-hifiberry-amp.0.analog-stereo (0, not suspended). Stream started. ^CGot signal, exiting.cy: 2288469 usec. pi@raspberrypi ~ $ top top - 16:08:16 up 8 min, 3 users, load average: 0.71, 0.71, 0.37 Tasks: 93 total, 1 running, 92 sleeping, 0 stopped, 0 zombie %Cpu(s): 7.2 us, 9.4 sy, 0.0 ni, 83.1 id, 0.0 wa, 0.0 hi, 0.3 si, 0.0 st KiB Mem: 447856 total, 154452 used, 293404 free, 15052 buffers KiB Swap: 102396 total, 0 used, 102396 free, 78044 cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2355 pulse 9 -11 87984 5824 3540 S 7.9 1.3 1:03.57 pulseaudio 2606 root 20 0 26376 15m 4760 S 2.0 3.5 0:10.32 Xorg 2772 pi 20 0 4668 1388 1040 R 1.3 0.3 0:04.61 top 2900 pi 20 0 83540 2764 2264 S 1.3 0.6 0:00.64 paplay 2761 pi 20 0 113m 9.9m 7708 S 0.7 2.3 0:04.76 lxterminal feel good music and as you can see above the CPU usage from pulseaudio is normal.

The only difference between the two wav files is that the first has a sampling rate 44100Hz and the second 48000Hz. what do you think about? -- You are receiving this mail because: You are the QA Contact for the bug.
