It didn't work on my PW3 7th generation G090G1 firmware 5.12.3

I searched the file system but couldn't find gst-launch anywhere.

It worked perfectly on my PW4. Thanks for a such a great extension.

It worked perfectly on my PW4. Thanks for a such a great extension.

Interesting. On my PW4 in ssh which gst-launch returns /usr/bin/gst-launch, so I gather this doesn't show the same on your PW3. Do you have a gstreamer-0.10 library with libgstaudiosrc.so and libgstmixersink.so in it?

Does Audible work on you PW3? I found that on the PW4 this was supported via gstreamer and the above noted libraries. If they are somewhere else on the PW3 it ought to be possible to fix this. If not, it will take finding out how Audible is supported there.

The strings I saw in the mixersink led me to think it would work with USB-OTG as well. That might be another possibility, provide the gstreamer modules as well for PW3.

is AAC streaming support on the agenda? or not so much.

[arooni]

this is pretty amazing. here's my updated menu.json with some of my favorite somaFM stations (hardly ever any commercials). crazy to be able to background play music while playing chess or reading my book. what a device!

many thanks!

That would require adding support for it to sox. At this point I have simply tracked down binaries from Debian Jessie for armel architecture from their repository. Adding AAC support would require obtaining the sox source, adding AAC support from somewhere and building the binary. That is beyond my capabilites at present. Perhaps someone else cound do so and I could incorporate their binary.

well a slow clap is deserved for all your efforts thus far!

No, none of these.

As documented by Amazon, Audible is not supported on the PW3.

Since you have a PW4 I would try copying the gstreamer binaries to the PW3 and place them with the sox binaries and libraries. You will of course need to edit the script to call gst-launch. Check with ldd to see if there are any other libraries required from the PW4. If this works it ought to be able to package an add-on for the PW3 for this.

[dhdurgee]

Was that executed on the pw4? If so, does it show the same on the pw3?

I had another thought occur. What audio can you play on the pw3, given you say Audible is not supported? If they are establishing a somewhat normal audio environment then sox might be able to use it directly. You can test this by copying sox to play in the same directory. Then try ./play /mnt/us/music/Mutlitudes.mp3 and see what happens.

On the PW3

Old experimental stuff:
- using alsa to play and record .wav. Packaged in a Kual extension
- espeak on <= 5.8.11 firmware when it still supported .azw2
- A speaking clock, packaged as another Kual extension, using flite tts

Ah. If alsa is supported it should be possible to get this working without gstreamer. Definitely try copying sox to play and invoking it as:

LD_LIBRARY_PATH=./library ./play /mnt/us/music/Multitudes.mp3

If it works great, then I need to figure out how to detect if alsa is supported and customize the scripts. If it doesn't work then add a -V3 option and see what it says.

Dave

[PoP]

More details please, copy what, where?

I have alsa (aplay, amixer and arecord) in /usr/bin/ and seemingly aplay can play more than wav:

[dhdurgee]

Sox (and its play renamed/linked version) will work directly with alsa, so no need to pipe it there instead. As I don't have a pw3 I can't test things directly here and have to rely on feedback from you and others. So I would in particular like you to test the ./play command and see if it works or not. I would also be interested in the output of which alsa on your pw3, as I think that might allow me to detect if it is available for me to use.

Hi, a noob question, but are you using VoiceView to connect bluetooth headset or is there any other way ? With VoiceView I had to double click everything to select and it's not a good experience when you listen to mp3 audiobook and try to open the ebook page.
