Older slingbox connected but no audio

[idenny1]

Hi, Thankyou for your work. I have a older slingbox model SB240-100 connected video is working but no sound. I am going start looking at your code slingbox_server.py probably something in the audio header when I have time. Any ideas what to start looking at?

Thanks

You can try the 350/500 slingbox type. If you want to there's some parsing of the Solo header to hack some audio stuff but I just cloned some existing code and not really sure what it does,except it works.

Line 446 if Solo: tbd = 0 audio_header = b'\x91\x07\xDC\xB7\xB7\xA9\xCF\x11\x8E\xE6\x00\xC0\x0C\x20\x53\x65\x72' audio_header_pos = first_buffer.find( audio_header ) + 0x60 # find audio hdr first_buffer[audio_header_pos:audio_header_pos+10] = pack("H 8x", 0x9012)

Thanks for the quick reply. I changed the following:

config.ini: sbtype=Solo

slingbox_server.py:

changed line 448 audio_header = b'\x91\x07\xDC\xB7\xB7\xA9\xCF\x11\x8E\xE6\x00\xC0\x0C\x20\x53\x65\x72'

to 448 audio_header = b'\xA1\xDC\xAB\x8C\x47\xA9\xCF\x11\x8E\xE6\x00\xC0\x0C\x20\x53\x65\x68'

Now audio is working. Not really sure what the change does other than tells the code where the audio stream starts I guess.

I am not a python coder but if we add and sbtype for "SB240-100" and another "if SB240-100:" with the different audio_header.

Thanks

Will do. Many thanks. It will be in the 3.08 release coming soon.

A quick question, how did you come up with that magic string?

[idenny1]

I uncommented line 442 442 # print( 'FIRST', type(first_buffer), pbuf(first_buffer)) Which displayed hexcode
