Hi, just a shot into the dark, maybe it's not ALSA, but Meltdown and Spectre mitigation. I don't know if firmware/microcode is updated or KAISER or KPTI patch sets are applied to the kernel used by your distro's release, neither do I know if they affect DSP load. However, Meltdown and Spectre mitigation could have impact on performance.

[Alsa-user] ALSA: Unknown device state '3'
I use a piece software called ecasound to push a stream from digital input to the output. I've been using it on RPi box with Raspbian since "Jessie" release. After updating it to "Stretch" I started to get such error messages when I run ecasound like this "/usr/bin/ecasound -B:rtlowlatency -b:256 -f:32,2,48000 -i:alsahw,1,0 -o:alsa,softvol": > ALSA: Unknown device state '3' > ALSA: playback xrun handling failed! It happens when an input stream is stopped. I need to restart ecasound to get it working. I guess something is changed in ALSA in Debain "Stretch", because in "Jessie" I didn't have such issue. Is there a way to prevent such behavior? __ Best regards, Dmitry Misharov -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ Alsa-user mailing list Alsa-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/alsa-user
