No sound output from USB mono sound card,when using gmrender #238

Closed syb999 closed 3 years ago

syb999 commented 3 years ago

But mpg123 supports this USB mono sound card, it can play MP3 normally. How do I fix it?

mill1000 commented 3 years ago

gmrender-resurrect uses Gstreamer under the hood to handle media playback.

See if you can use gst-play-1.0 or speaker-test with your USB sound card. Here's an example: https://github.com/hzeller/gmrender-resurrect/issues/205#issuecomment-580846698

It's much more likely this is an ALSA configuration issue.

Thank you for your reply. gst-play-1.0 can output sound with my usb mono sound card. But gmrender still no sound output.

Can you turn on logging with --logfile=stdout? Most likely the wrong device is being selected for output.

in fact,the gst1-libav package has built-in decoder: MPEG-4 AAC

Thx for your help,the problem has been solved.

Check openwrt/feeds/packages/multimedia/gst1-libav/config.in: config GST1_LIBAV_PATENTED bool "Include patented codecs and technologies" default BUILD_PATENTED

Set config GST1_LIBAV_PATENTED=y for support MPEG-4(AAC).
