Hi all new here, and loving my new picrawler, however after getting the ai working perfectly i can hardly hear the replies. I have run i2samp.sh a few times and rebooted etc. the sound is playing just very quietly. i have modified the OpenAi config as per below. Please help ass i also notice when checking the sound i only get front right not front left

OpenAI Configuration

# =================================================================

# Language configuration for STT

LANGUAGE = # Empty list means auto-detect, can specify like [‘en’] or [‘zh’]

# Volume gain for TTS output (increased for better audibility)

# Note: Values above 8dB may cause audio distortion

VOLUME\_DB = 6

# TTS voice selection: “alloy”, “echo”, “fable”, “onyx”, “nova”, “shimmer”

# [https://platform.openai.com/docs/guides/text-to-speech/supported-languages](https://platform.openai.com/docs/guides/text-to-speech/supported-languages)

TTS\_VOICE = ‘nova’

# OpenAI API timeout (seconds)

OPENAI\_TIMEOUT = 30

# Sound effect actions (actions that produce sound effects)

SOUND\_EFFECT\_ACTIONS =

Please execute the command sudo amixer -c 1 sset PCM 100% to see if you can increase the volume.  
Alternatively, you can run the alsamixer command, press F6 to switch audio devices, use the ↑ and ↓ arrow keys to adjust the volume, and press ESC to exit. Check if the speaker volume can be increased.  
We recommend reinstalling i2samp.sh with the following commands:

cd ~/picrawler  
sudo bash i2samp.sh  
Then run the audio example to see the results.
