Doesn't matter what one calls it, the only point that matters is "Where" the volume control is actually happening: If it is being done in the Digital Domain, the stream is no longer Bit Perfect. If it happens in the analog section, then the data has been decoded, the DAC has done its job, and the analog level is being adjusted which doesn't affect the Bit Stream because all that was already completed. Almost all DACs and Digital Output devices that can control Volume do so in the digital domain all at the cost of Bit Perfect. Off the top of my head, I have only seen one DAC that had volume control that didn't affect the bit stream because it was actually a DAC/Pre-amp so the volume control on the remote controlled the analog pre-amp's various inputs as the output of the device went directly to the amplifier. *iPhone* Media Room: ModWright Platinum Signature Transporter, VTL TL-6.5 Signature Pre-Amp, Ayre MX-R Mono's, VeraStarr 6.4SE 6-channel Amp, Vandersteen Speakers: Quatro Wood Mains, VCC-5 Reference Center, four VSM-1 Signatures, Video: Runco RS 900 CineWide AutoScope 2.35:1, Vandersteen V2W Subwoofer Living Room: Transporter, ADCOM GTP-870HD, Cinepro 3K6SE III Gold, Vandersteen Model 3A Signature, Two 2Wq subs, VCC-2, Two VSM-1 Office: Touch with Vandersteen VSM-1s Kitchen: Touch in-wall mount w/ Thiel Powerpoint 1.2s Bedroom: Squeezebox BOOM Bathroom: Squeezebox Radio Around the House: SliMP3, SB1, SB2, SB3 Ford Thunderbird: SB Touch, USB drive Ford Expedition: SB Touch, USB drive iPhone's Profile: http://forums.slimdevices.com/member.php?userid=13622 View this thread: http://forums.slimdevices.com/showthread.php?t=108191 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

Agree, but my question is: since my DAC is capable to control the volume and the documentation says that in case the player is capable of controlling the volume by delegate the DAC... then it is better. Looking aroud, seems that letting the player modify the volume it is called "software volume control", while controlling the volume by tellig to do it to the DAC is called "hardware volume control". My DAC come with a driver for Windows that install a little app in the Windows bar and so, for example with JRiver, I disable the software volume control and control the volume with this little app that communicate to the DAC itself. Is there any way with pCP to do that? I mean disble the software volume control and enable the hardware one? steff's Profile: http://forums.slimdevices.com/member.php?userid=66870 View this thread: http://forums.slimdevices.com/showthread.php?t=108191 ___ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix

[SlimDevices: Unix] rpi3+pcp3.22+LMS causes transporter & SBradio to jump in and out of LMS
Hello community :) After following the pcp project for a long time I decided to take the next step after spotify pulling the plug and the amazing Mr. Herger coming to the rescue once again. (many "thank yous" Michael!) First I'll start by saying I was *very* impressed by the simplicity effectiveness and performance of the rpi+pcp+lms combo. I only made a quick test with pcp as a player (usb connected speakers) and as I expected all this time one of my future projects will definitely be a pcp portable player with all the jivelite+touch screen goodies etc So big kudos to the pcp team and many "thank yous" as well. Keep up the amazing progress guys! Now since my current needs called for a server combo I set aside the speakers and focused on serving my transporter + radio (boom is currently offline for the time being but will be joining the herd soon) All _sort of_ worked as supposed to but there are some isssues: - the connected to lms clients (transp + radio) appear to connect and disconnect every 10 secs or thereabout...no this does *not* appear to be an _exact_ period but more of a rough description of the behaviour ie client is connected..after 10 secs or so disconnects.after 1sec connects again...after 10secs disconnects etc - everything is wired nothing is wireless. a ping -t to the pcp shows no dropouts and all latency is 0ms as expected - when a player is playing a radio stream there are *no* audio-dropouts during all this connecting-disconnecting..I assume because of having full buffers and because the disconnection lasts only 1 sec or so - the observation of said disconnections came while managing the radio through orangesqueeze where one can see the radio appearing and disappearing from the list of available players. -this can not be an orangesqueeze problem since the transporter gives an audible sign whenever it loses connection to server (the digital outputs/inputs make a distinct clicking sound upon disconnection/reconnection) -like I mentioned all is wired and I also tried connecting the rpi to a different ethernet port using a different cable So these are my strange findings so far and I hope someone can chime in with some suggestions cause I'm out of ideas.

Re: [SlimDevices: Unix] Debian package fails to run
Didn't say it was Ubuntu's problem. They upgrade, you have to upgrade. The LMS already ships with huge blobs of precompiled code supporting many different versions of perl, that's the main reason it's huge in the first place. One more required (two if people want i386 aswell).

Either you stick with the trailing edge and write LMS to be 5.8 compliant. Or if that isn't palatable, then choose a version of perl you are happy with and bundle that in with the deb. If the only release cycle is a series of nightly builds then bundle everything that its required and you avoid a moving target. OR have stable releases, if you provide package bundle they should work out of the box. This isn't Ubuntu's problem - I've not upgraded Ubuntu. I've moved from LMS 7.9.0 to 7.9.1.

Re: [SlimDevices: Unix] BitPerfect
Set the volume to 100, that's all you need. But, remember, software volume control is good as long as your gain chain is ok. It's done in 24 bits, so any rounding errors are several orders of magnitude below the noise floor introduced in even the best amplifier chains.
