When viewing your outgoing email to the list, are the missing bits in the text/plain alternative part of your outgoing copy? Or was KMail unable to represent your words in text/plain? The list's current configuration has it take a multipart/alternative email, e.g. with text/plain and text/html parts, strip that down to just one alternative, probably the text/html as it's indicated to be the "better" representation by coming second, and then convert text/html to text/plain before sending out. It's possibly the omitted bits were due to some fancy HTML you produced. Ideally, send just text/plain to the list so the list won't interfere. That's how the list used to work IIRC, before Mailman fept some creatures.

I was only using .wav, because the Tutorial used aplay and that doesn't support mp3. Now I am trying to work out how to direct the output of mpg123 to the same audio devices. The format of the command seems to be different to aplay and it keeps defaulting to the PC sound card. Any thoughts on that anyone? -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2016-12-06 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR

Hi Terry, > I installed sox, but found the man page a bit dense It just needs reading many more times. :-) sox has a soxexam man page too with examples so you can then work backwards and look at the options in the reference sox(1). BTW, that soxexam mentions sticking with PCM if you're doing multiple modifications and that's probably good advice as WAV files can contain MP3 lossy compressed sound and not just PCM. soxexam also introduces some of the effects sox can produce; perhaps they might be helpful if you need more of an "echo", etc. Cheers, Ralph. -- Next meeting: Bournemouth, Tuesday, 2016-12-06 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR

You need to produce a new WAV file. See sox(1) IIRC.

Re: [Dorset] Syntax for aplay
For some reason the listserver stripped out the middle part of my message (when I view what I sent, it only shows up if I view html, but there wasn't nay html in the message) ;-( Most of the missing text consists of the man page fragment for -f, so that is available to all. Apart from that, the following line was also stripped out: 'I've tried every possible incantation of -f that I can think of, but always get the same result.'

[Dorset] Syntax for aplay
Hi, I've just received a set of these: https://thepihut.com/products/usb-audio-adapter[1] As far as I can tell, these are identical to the ones sold by Modmypi and others, so I've been trying to get them to play using the tutorial I found on the Modmypi site. Initially, I'm doing this on my PC for convenience. I can identify the devices and aplay attempts to play the file, but complains that I've asked for the wrong format: ../Playlist1$ aplay -D hw:3,0 01_Wedding_March.wav Playing WAVE '01_Wedding_March.wav' : Signed 32 bit Little Endian, Rate 44100 Hz, Stereo aplay: set_params:1297: Sample format not available Available formats: - S16_LE I can get the file to play to the default audio device on hw:0,0 without complaint, but that of course is my PC sound card. The man page for aplay says: -f --format=FORMAT So my question is twofold: 1. What is it that doesn't like the format; the device or the tool? 2. If it's the tool; how do I write it to make it work. BTW. I really want to do this using mpg123 eventually, but I haven't found a tutorial to help me make that work, so I started with this. -- Terry Coles [1] https://thepihut.com/products/usb-audio-adapter -- Next meeting: Bournemouth, Tuesday, 2016-12-06 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
