Is anybody else working on PCM playback for Archos? Or there is no hope...

I've exactly same problem, the chip hangs after the run command. Do someone else get it working ?  ???

Thanks in advance,

pixelma:
I'm not sure what you are trying to achieve here, but both plugins are now in SVN - wavplay and wavrecord.

If you want to write your own code or plugin, you could take a look at the source of these two (both are in apps/plugins).

freud:
Thanks for your reply !

Yes, I'm working on a new hardware based on MAS3539F Decoder chip, decoding and encoding part (ADPCM) works fine from/to an SD memory card. My main processor is a NXP LPC2378 (ARM7 CPU) which handles man machine interface (LCD, rotary encoder, USB mass storage, Ethernet TCP/IP, SD card driver and bitstream to/from the micronas chip). The project is working except to few bugs to be fixed. I saw a nice plugin from the Rockbox project which allow the WAV record/playback (PCM code provided by Archos) and I would like to test it on my hardware (recording part in WAV rather than ADPCM is a nice feature since I'm a guitar player and need to get highest sound quality).

I studied the plugin code (PCM Audio Recorder) and my code is similar to the RockBox ones. After transferring the PCM code, I got same issue as Max90125.. the MAS chip hangs after a Run Command  ??? I'm pretty sure the MAS DSP core is same between MAS3539F and MAS3587F chip (they are both same pinout though, so it's easy to swapf one by the others ;D)

My other solution would be to use the I2S interface in my ARM7 to connect a nice codec (DAC/ADC) to play/record wav. As I found out the MAS could do it, I prefered tested before :P but with no success...

edit : it freezes up when i try to record in mp3 as well.

maybe a bad hard drive?

it seems to happen around 1 meg of recording.

wow.  I'd given up hope when the last time I looked for this thread it had dissappeard.  (It was in my bookmarks for ages, I presume there must have been a messageboard software update or something since my bookmarking it)
