I'm looking for a similar setup where I stream Hi-res/Master Tidal from a Windows server via Waveinput to my Squeezebox Touch, but I only get buffering and white noise when configuring Waveinput to higher flac qualities than 16/44,1 in custom-convert.conf.

Not all alsa devices are "active" as that depends on the Wolfson setup scripts but they can be accessed using Alsa and and you can play to or record from these these alsa device but nothing may come out or rubbish may be recorded if the Wolfson card is not setup correctly. In this sort of situation, I normally take a break and then after a day or so review all the information gathered so far.

Here is Reset_paths.sh (used to reset the AlsaMixer to output nothing as far as I understand): 16986 This is Record_from_lineIn.sh, which I understand allows ALSA to see the Line In source in order to record (with any program, not just arecord): 16987 And this is Playback_to_Lineout.sh, which configures ALSA to allow you to play out through your Line Out (with any program, not just aplay): 16988 As for the kernel, I really don't know where it comes from.

This is a standard alsa program and it interacts with ALSA API.

I ran that C code now to try to determine the capabilities of my card. First, I put the ALSA driver in as the argument, compiled and ran the code, and then put in my Wolfson card as an argument (listed by aplay as sndrpiwsp) and ran it again. Below are the results: 16982 Even though the program lost its mind and printed lines and lines about invalid arguments after I ran it for my Wolfson card, you can still see that it supports 24 bits and 192 kHz.

A plugin that is able to play from a netcat TCP/IP stream won't care where the stream comes from so the plugin is general purpose and source system agnostic. It is up to user to create the source in the case of RPI if recording audio from an external source then some extra hardware is needed. This RPI user has a Wolfson card which has both an analogue and digital input.This sort of plugin would have clean netcat interface and so user will never have to fiddle with LMS plugins or code. 2.

While the streaming with vlc would also (hopefully) work too, I wouldn't be the only one using this solution, and I wanted to have a nice interface and an easy-to-control method as well as synchronization of the playback streams. I have a feeling that would be complex with that direct streaming method. > Remove the PCM line as there is no easy way this is going to work. > Remove the MP3 because even though it can be made to work - why waste > time working out the correct lame option settings. > After this suggestion, I wanted to make sure that whatever command I have in the custom-convert.conf file would be more or less usable from the command line. I did several tests with this, and ran into problems. I tested playback of the .flac files I created with mplayer, since arecord/aplay doesn't support flac files. I downloaded a 24/192/2ch flac test file from Linn Recordings to ensure that I could playback a 24/192/2ch file locally on my server unit, which I was able to do through mplayer with no problems. However, when I tried to create a line close to what I'd be using in the custom-convert.conf file using "arecord -d0 -c2 -f S24_LE -r 192000 -traw -D hw:0 | flac -cs --endian=little --sign=signed --channels=2 --bps=24 --sample-rate=192000 --compression-level-0 - -o flac_raw24.flac", I simply got static with warped music underneath. When I change the bits per sample (in both the arecord portion and the flac portion) though, mplayer plays back the file fine. These two behaviors also occur if I change the -t field to wav. Changing the sample rate doesn't change the behavior. The mplayer states that the file is s32le format (which I thought might be a problem), but it also states that the working flac file from Linn is s32le. Also, I tried to simply record 24 bit and 16 bit audio to a wav file (not using the flac conversion) and play it back with mplayer. mplayer will sound the same as the 24 bit flac files I created (static, warped music), but when I play it through aplay, it plays fine. Does anyone know why the flac conversion is crapping out like this at 24 bits? The Wolfson card can definitely support 24/192/2ch capture/playback. I know this thread is running a bit off topic, but I feel like this is the last hurdle before a working solution. I've attached screenshots of all the flac conversions/wav captures/playbacks I attempted and the mplayer results when I play them. test192.flac is the Linn test file: 16968 16969 16970 16971 16972 Thanks for all the responses so far!

Other than that, would creating a source stream using (eg) vlc work ? that source stream could then be a radio feed fed back for LMS - if you are not sensitive to delay, that would probably work, I think LMS 7.7.2 - 5 radio, 3 Boom, 4 Duet, 1 Touch, 1 SB2.

Or is there a better way to modify it? Remove the PCM line as there is no easy way this is going to work. Remove the MP3 because even though it can be made to work - why waste time working out the correct lame option settings. The flac command line to encode the stream has to have option telling flac that the input is pcm 192 24bit 2 ch (or whatever you are using) and then the output will have a header. If you wish to support downsampling - you should look at main convert.conf file to how to do downsampling using flac. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=102689 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Since this is a analog source - why did you mention multi channel multiplexing in the other thread - I had assumed you were recording from the digital input. If the recording is fixed at 192/14/ch and it never changes then using Flac as the output stream means the Wavin plugin conf file can be hardcoded to your application and no changes are need to plugin. > Thats a feature Squeezeboxes always lacked to be able to route analog > inputs trough the house , quite usefull , for exqample LP playback (but > that wont need 24/192 ) . The WaveInput plugin requires LMS to be running on the device. The use-case I saw was remote device with no LMS such as Touch player - and user wants to route audio form remote player to LMS which then can then be played on any or all SB players. For personal use, I did a rough version of plugin to do this where the player used netcat to create a Flac stream from audio input streamed over a specific tcp/ip socket and the modded version wavinput which would create a netcat to connect to player when remote audio streaming was required. Using netcat means remote audio port can be on a Windows, OSX or Linux box (e.g. Touch). bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=102689 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins

Re: [SlimDevices: Plugins] Looking for plugin which parses stream for sample rate/bits per sample
A bit of background would help here I'm sure. I have 3 Raspberry Pi units. One has a Wolfson audio card on it, and the other two have HiFiBerry DACs attached to them. I have a high quality audio source (capable of outputting 24/192/2ch analog audio) which I want to be able to pipe to the rest of my home, similar to a Sonos system. I wanted to do this using the RPi with the Wolfson card as a server which can pull this HQ audio stream in at 24/192/2ch and send it over the network to my 2 RPi units with the HiFiBerry DACs. The Wolfson card is capable of 24/192 recording/playback and the HiFiBerry DACs are capable of 24/192/2ch playback. After researching several solutions based on my requirements (playback sync, reliable stream, don't care too much about latency as long as it's within 5 seconds), I decided on using LMS on my Wolfson Pi with bpa's WaveInput plugin. Now, it appears that the plugin requires some modification if I want to allow this 24/192/2ch capability. As for what I want, I don't care whether the stream is sent as PCM or FLAC. As long as I get that 24/192/2ch playback at the sources. If I understand it, the format of the custom-convert.conf file in the WaveInput plugin needs to be written using a very specific format (including sections for PCM, mp3, and FLAC). However, if this can be modified to just send FLAC and I can skip this problem with PCM not containing format information in the headers, that would be great.

Re: [SlimDevices: Plugins] Looking for plugin which parses stream for sample rate/bits per sample
It was late when I posted the last suggestion but having slept on it I think setBitrate suggestion won't work as you need to set the sample rate and not the bit rate. Also I feel that the bit by bit approach of "give me a hint" will not work as I don't have the specific knowledge and all I am doing is suggesting the starting points I would try. However, your level of knowledge/skill means that I'm wasting your time as you're not able to recognise a dead end approach quickly. To get some sort of solution quickly I think you need to stream to player Flac not PCM and that you could look at the Forum threads which do upsampling of CD quality stream/file to IIRC 96kbits or192kbits to see if there are any special trick etc. Having a working Flac solution will give you time to see if a PCM one is possible. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=102689 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
Re: [SlimDevices: Plugins] Looking for plugin which parses stream for sample rate/bits per sample
I'm up to my eyes with real world and cannot be back to this until next week. You questions need time to look at LMS code as I don't know the answers offhand as you are asking for functionality which AFAICT nobody has done before so it is possible, LMS cannot do it at the moment. IIRC the getConvertCommand2 cannot be called by a plugin ProtocolHandler - the routine the plugin handler calls is tokenizeConvertCommand2. However reviewing that part of the plugin has given me the idea that perhaps the routine Slim::Music::Info::setBitrate (see how it is used in iPlayer plugin parserMetatdata routine) might do the trick in the "new" subroutine of the WAVIN.pm file just after Slim::Music::Info::setContentType. It would probably be quicker to write code and test (with various LMS logging enabled to confirm the action) than to trace LMS code. bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=102689 ___ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
Re: [SlimDevices: Plugins] Looking for plugin which parses stream for sample rate/bits per sample
I have potentially found something that could help. The TranscodingHelper.pm file. Could the functionality I want be in here? In particular, a subfunction called getConvertCommand2. It looks like there could be a sample rate and format override. Could someone take a look in there and tell me if that's it?

Format info therefore will not be available as there is no header. Also OP mentions downsampling and also multiplexed stream so I am not sure what exactly the origin of the stream except coming in on Wolfson audio card. I am not sure how to achieve this in a LMS plugin and I suggested that a parseMeta data is likely hook to provide this info to LMS from a plugin (it si the approach I would look into first) since examining the stream is not possible. However since I ( and AFAICT nobody else) has done this it is an educated guess. I am v. busy at the moment (Christmas, tax returns, end of year audit ...) and haven't got the time to wade thro' LMS to investigate and verify and then give a ready made solution.

LMS does scan streams before they are played. That information should be available then. Without more information it'll be hard to help you. Maybe you can ask the person who wrote the existing plugin you try to modify?
