I let it run for three minutes. During this run I've heard 9 drops with 5 of them being either long or double (sounded as two clicks one right after another). I actually ran it twice, but the first time I lowered volume with "mixerctl outputs.master=150" and that led to having less drops. I didn't actually mesured the effect, but I can if it would help. At the moment of volume switching I also hear the drops (as far as I can get, the drops of a higher of switching volumes either on gettting volume lower or higher). The output of the max volume run (I actually have the volume at max by default, because I use built-in speakers that are actually weak): % ./audrops pre=16 ch=2 bpf=4 block_size=4096 rate=48000 block_usec=21333 early return at 1279710059.088985: 416 < 21333 early return at 1279710059.089085: 100 < 21333 late return at 1279710065.556951: 559520 > 21333 late return at 1279710099.639360: 571912 > 21333 early return at 1279710099.643480: 4120 < 21333 late return at 1279710109.588648: 426470 > 21333 early return at 1279710109.588793: 145 < 21333 early return at 1279710109.588900: 107 < 21333 early return at 1279710109.589009: 109 < 21333 early return at 1279710109.589134: 125 < 21333 early return at 1279710109.589252: 118 < 21333 early return at 1279710109.589372: 120 < 21333 early return at 1279710109.589448: 76 < 21333 early return at 1279710109.589513: 65 < 21333 early return at 1279710109.589581: 68 < 21333 early return at 1279710109.589650: 69 < 21333 early return at 1279710109.589718: 68 < 21333 early return at 1279710109.589785: 67 < 21333 early return at 1279710109.589854: 69 < 21333 early return at 1279710109.589922: 68 < 21333 early return at 1279710109.589991: 69 < 21333 early return at 1279710109.590059: 68 < 21333 early return at 1279710109.590127: 68 < 21333 early return at 1279710109.590195: 68 < 21333 early return at 1279710109.590271: 76 < 21333 late return at 1279710144.015969: 549096 > 21333 early return at 1279710144.021564: 5595 < 21333 late return at 1279710149.541125: 570146 > 21333 early return at 1279710149.547019: 5894 < 21333 late return at 1279710161.240031: 556813 > 21333 early return at 1279710205.846800: 7957 < 21333 late return at 1279710212.051492: 551253 > 21333 early return at 1279710212.054930: 3438 < 21333 early return at 1279710236.439423: 10074 < 21333 ^Cpre=16 ch=2 bpf=4 block_size=4096 rate=48000 block_usec=21333 bytes written = 34627584 bytes processed = 34545664 bytes errors = 73728 bytes buffered = 8192 34627584 == 34627584 ? run time = 183.473831 s avg rate = 47071
