Hello, I've been having a playback problem recently, and have been looking at trying to determine the cause. On my PC, audio is playing continuously, mostly for background noise. Recently I've been trying upgrade to a newer PC, trying to keep things as similar as possible. For some reason audio playback gets stuck after a long time (it repeats the last half second of audio, and the player's time counter stops increasing). I can stop the player and restart it again, and it will work for many hours. I have the player set to use plughw:0,0 as the output. One of the behaviors I see in /proc/asound/card0/pcm0p/sub0/status is that the hw_ptr and appl_ptr are very different: state: RUNNING trigger_time: 154.109259874 tstamp : 64590.994415958 delay : 22048 avail : 0 avail_max : 0 ----- hw_ptr : 1444936032 appl_ptr : 20352 When I 'cat status' a number of times, the only field I see that changes is the tstamp. I'm curious as to whether these ptr values are reasonable after a long playback (and if an update to alsa-lib/alsa-driver or tweaked parameter to a module might prevent it from getting stuck). When I restart the player, I see that the ptr values are more reasonable (hw_ptr + delay = appl_ptr). The OS is Debian Lenny, with alsa-driver and alsa-lib both at 1.0.19 (a little older, will upgrade over the weekend if that should help) The old PC had a VIA chipset/CPU, with the VIA 8237 controller and the ALC655 codec. The new PC has an Atom D525 chip, with the Realtek ALC662 rev1 HDA codec. Thanks! -Ron ------------------------------------------------------------------------------ Beautiful is writing same markup.
