alsaloop doesn't pass sound with libsamplerate resampling on raspberry pi 5
by GitHub issues - edited 10 Feb '25

10 Feb '25

alsa-project/alsa-utils issue #291 was edited from willangley: Hi alsa-utils team! I'm using `alsaloop`s on a Raspberry Pi 5 as part of a slightly ridiculous signal chain: * Yamaha P-525 keyboard * USB C-to-A cable * Raspberry Pi 5 * USB A-to-B cable * ESI U24XL * SPDIF in/out * Focusrite Clarett+ 4Pre * ... * MacBook Pro [Why? The analog Aux In/Aux Out on the keyboard have an always on loopback connection, which is undesirable when playing to a video meeting. The USB port has user controllable loopback.] Two alsaloop processes run on the Pi, one moving sound from the computer to the piano, one moving sound from the piano to the computer. Both run under `supervisord`. I've got them running at acceptable latency — RTL Utility says 40ms from my MacBook Pro. But I haven't been able to get any of the high quality resampling options working -- everything other than add/drop stops passing sound within a few seconds. I'm surprised; this Pi should be powerful enough to handle this. Any ideas how to troubleshoot it? I didn't see errors in logs at the default log level. Thank you!

Soundblaster G8 USB Audio not working correctly
by GitHub issues - opened 07 Feb '25

07 Feb '25

alsa-project/alsa-lib issue #437 was opened from Starfoxfs: Soundblaster G8 works partly under Linux Mint 22.1 Cinnamon. Audio playback works in Analog stereo or Duplex mode with headphones and these are displayed as Speakers. Digital SPDIF Out works and also the switch button between headphones and Digital out to external Speakers (only with pipewire not with Pulseaudio). What doesn't work is the Direct Mode and all the Crystalizer surround settings as well as output in virtual 5.1 or 7.1 sound. Microphone doesn´t work, if it plugged in i have no sound at all.

soundwire : LnK SoundWire Protocol Analyzer on Linux
by Muni Sekhar 06 Feb '25

06 Feb '25

Hi all, I hope this message finds you well. I am planning to use the LnK SoundWire Protocol Analyzer on a Linux platform. However, I am uncertain whether the current Linux kernel includes the necessary SoundWire drivers to support this . I would appreciate any guidance on how to use the LnK SoundWire Protocol Analyzer with the Linux kernel, as well as information on the specific device drivers required. Could you please provide details on: The compatibility of the LnK SoundWire Protocol Analyzer with the Linux kernel. The steps to set up and use the analyzer on a Linux platform. The necessary device drivers and any additional configurations needed. Thank you for your assistance. -- Thanks, Sekhar
