Re: [SlimDevices: Plugins] Squeezelite on Pi4 playing way too fast
dmix is the root cause of your problems and I think you don't need to use dmix. You want the audio out to play sometimes from the TV and sometimes from LMS. I presume you do not need it to mix the TV and LMS audio simultaneously ? If that is the case use the basic ALSA device for audio out and just use -C at a low value say 1 or 2 secs. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=111486 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Re: [SlimDevices: Plugins] Squeezelite on Pi4 playing way too fast
I think the "-C 5" probably does nothing except close the dmix device between uses - so always handle the first stream correct but not when mixing. Not really part of a full solution. You may need to use "-a" to restrict the sample size for Alsa if sample size is the problem with dmix. To force LMS resampling use -r and specify the same bitrate as the dmix default value. This should restrict squeezelite to playing at a single bitrate - LMS will only send stream at this rate. You need to make sure that all non LMS stream on the dmix device are also at the same bit rate as the LMS stream. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=111486 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Also if you do not know Pulseaudio you'll need to read up as otherwise your swapping one problem for another. No need for C3PO - LMS will do all the necessary resampling if it is told the player can only handle specific bit rate.

My MP3 collection is a HUGE mixed up mess that needs to be seriously cleaned up and purged for exactly the same reasons you just mentioned. Sadly, I've got an increasingly nasty case of tinnitus that I've had since childhood, but has gotten somewhat worse with the birth of my 2 kids in the last 5 years. Perhaps it's the screaming. Perhaps it's that I'm just turning 50. At any rate, it will be interesting to see, once I get these files cleaned up/upgraded, if I'll be able to tell the difference between 128k and something as delicious sounding as FLAC. However, I'm still holding on to my vinyls. They're safely hidden away here at the house where no meddling kids can find them. A couple more years of maturity in these boys and I'll bust out the turntable and turn these boys on to some of my gems like Miles Davis, John Coltrane, Mingus, and Monk... Maybe even throw in some Allman Brothers, Deep Purple or ELO. Then again... Spotify has 320k doesn't it... Makes me think about deleting or at least seriously purging the MP3 directory. noexit's Profile: http://forums.slimdevices.com/member.php?userid=66502 View this thread: http://forums.slimdevices.com/showthread.php?t=111486 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

I recall adopting this on the Joggler half a dozen years or so ago, by customising the -asound.conf- file, and probably posted a how to suggestion on the Joggler forum. But (a) I dont know how to implement in the context of Squeezelite, and (b) I recall its only needed if the ALSA device is shared amongst different applications. So unless the OP has that requirement a simpler approach probably suffices.

Re: [SlimDevices: Plugins] Squeezelite on Pi4 playing way too fast
You guys are incredible detectives and I'm learning an awful lot. I'm very glad I decided to take this project on and engage the support of the forums as it's filling in a lot of the knowledge gaps I've had around my love of both computers and audio. Here's what I've discovered: @Ronnie - Your suggestion of switching the Squeezelite Soundcard setting was well targeted: I changed the *SoundCard *line in */usr/local/bin/squeeezelite_settings.sh *from SL_SOUNDCARD="*dmix*:CARD=audioinjectorpi" to SL_SOUNDCARD="*hw*:CARD=audioinjectorpi,DEV=0". This made Squeezelite play at normal speed/pitch again (see results below). Of note, I DID leave on the *DEV=0,*" on the entry as it was already there. However, when I tried to simultaneously play another audio file in VLC, an error was returned in VLC stating that the audio device DMIX was "Busy". When I changed the entry back to DMIX the playback speed and pitch in Squeezelite increased again, but also, as expected, audio sharing was re-established across applications. @Bpa - Thanks for suggesting the details of the files. Note that both playback time and pitch are affected. As far as I can tell, the track isn't being played back through any kind of transcoders or processing. Or at least, I haven't set any up, so if they are they are part of the default install of my AudioInjector card, LMS or Squeezelite I suppose. The test file is an MP3 stored on a USB drive attached to a networked PC. However, I also notice that playback of a network stream (SomaFM, Venice Classic Radio) also renders the same problem affecting both speed and pitch. (I wasn't sure until I chose a Classic Rock radio station where I could hear familiar music - Tom Petty's Refugee as if he's 9 years old :rolleyes:). After a few minutes of playback I hear "corrections" in the stream dropping, skipping, stuttering. Of note, VLC's playback speed/pitch doesn't appear to be affected by DMIX. It seems that Squeezelite gets a little "excited" being hooked up to the ALSA Dmix plugin. If you guys like I could make an audio capture of the differences in pitch for your listening pleasure. 9 year old David Gilmore :cool:.

Re: [SlimDevices: Plugins] Squeezelite on Pi4 playing way too fast
The log shows the output device being opened at 44100. Usually when something is played fast - it is a 44100 being played at 48000 so speed increase is slight about 8% Sometime the issues is a mono file being played so track is played at twice the speed. Other rarer problem is sample size. What is the specific speed difference ? (e.g. how long does track to play vs what is the duration according to LMS) - the specifc difference will point at the issue. What does LMS say the characteristics of the problem track ? (i.e. drill down through GUI to get sample rate , sample size, number of channels). bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=111486 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Hi Michael Try changing squeezelite_settings.sh file contents: SL_SOUNDCARD="dmix:CARD=audioinjectorpi" to SL_SOUNDCARD="hw:CARD=audioinjectorpi,DEV=0" and adjust any other alterations to default settings ronnie Man in a van's Profile: http://forums.slimdevices.com/member.php?userid=43627 View this thread: http://forums.slimdevices.com/showthread.php?t=111486 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
