https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213687 Bug ID: 213687 Summary: Raspberry Pi sound: PCM channel gets dead ("play interrupt timeout") after 48 hours Product: Base System Version: CURRENT Hardware: arm OS: Any Status: New Severity: Affects Only Me Priority: --- Component: arm Assignee: freebsd-arm@FreeBSD.org Reporter: sylvain@sylvaingarrigues.com Hello, I am the happy owner of the raspberry pi 2, analogue sounds works GREAT but I've always had problem after a few days. I listen to music several hours every day with my Pi, if I play music everyday everything is fine, but I have noticed that if I don't play music for more than 48 hours, I get this error trying to relaunch music (no log before): pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead Any idea? I have this verbose log just before it dies (cut version): pcm0: WARNING: PCMDIR_PLAY DMA completion too fast/slow ! hwptr=44000, old=44000 delta=0 amt=0 ready=8192 free=119808 feed_root: (virtual) appending 3676 bytes (count=3676 l=0 feed=7524878) pcm0: WARNING: PCMDIR_PLAY DMA completion too fast/slow ! hwptr=48000, old=48000 delta=0 amt=0 ready=8192 free=119808 feed_root: (virtual) appending 1852 bytes (count=1852 l=0 feed=7524879) feed_root: (virtual) appending 1824 bytes (count=1824 l=0 feed=7524880) pcm0: WARNING: PCMDIR_PLAY DMA completion too fast/slow ! hwptr=52000, old=52000 delta=0 amt=0 ready=8192 free=119808 pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead Gonzo said in an earlier bug these WARNINGs are inherent to the way the raspberry pi sends sound to the firmware so I'm not worried about it. # sysctl -a | grep pcm: dev.pcm.0.dest: 1 dev.pcm.0.eq_preamp: +0.0dB dev.pcm.0.eq: 1 dev.pcm.0.bitperfect: 0 dev.pcm.0.buffersize: 0 dev.pcm.0.play.vchanformat: s16le:2.0 dev.pcm.0.play.vchanrate: 48000 dev.pcm.0.play.vchanmode: fixed dev.pcm.0.play.vchans: 1 dev.pcm.0.%parent: vchiq0 dev.pcm.0.%pnpinfo: dev.pcm.0.%location: dev.pcm.0.%driver: pcm dev.pcm.0.%desc: VCHIQ audio dev.pcm.%parent: # sysctl -a | grep snd hw.snd.maxautovchans: 16 hw.snd.default_unit: 0 hw.snd.version: 2009061500/armv6 hw.snd.default_auto: 1 hw.snd.verbose: 4 hw.snd.vpc_mixer_bypass: 1 hw.snd.feeder_rate_quality: 1 hw.snd.feeder_rate_round: 25 hw.snd.feeder_rate_max: 2016000 hw.snd.feeder_rate_min: 1 hw.snd.feeder_rate_polyphase_max: 183040 hw.snd.feeder_rate_presets: 100:8:0.85 100:36:0.92 100:164:0.97 hw.snd.feeder_eq_exact_rate: 0 hw.snd.feeder_eq_presets: PEQ:16000,0.2500,62,0.2500:-9,9,1.0:44100,48000,88200,96000,176400,192000 hw.snd.basename_clone: 1 hw.snd.compat_linux_mmap: 0 hw.snd.syncdelay: -1 hw.snd.usefrags: 0 hw.snd.vpc_reset: 0 hw.snd.vpc_0db: 45 hw.snd.vpc_autoreset: 1 hw.snd.timeout: 5 hw.snd.latency_profile: 1 hw.snd.latency: 5 hw.snd.report_soft_matrix: 1 hw.snd.report_soft_formats: 1 -- You are receiving this mail because: You are the assignee for the bug.help
