解决Travis CI Linux构建中alsa-sys找不到alsa.pc的问题

这个问题的根源很清晰：Travis CI的Linux虚拟机默认没有安装ALSA的开发依赖库，而alsa-sys crate需要通过pkg-config来定位alsa.pc文件，找不到这个文件自然就会构建失败。

你只需要在.travis.yml中添加一个针对Linux系统的依赖安装步骤就能解决，具体操作如下：

在配置中新增before_install字段，针对Linux系统安装libasound2-dev（这是Ubuntu/Debian环境下ALSA开发库的包名，Travis的Linux构建环境基于Ubuntu）：

修改后的完整.travis.yml配置如下（我标记了新增的核心部分）：

language: rust
cache: cargo
rust:
  - stable
matrix:
  allow_failures:
    - rust: nightly
  fast_finish: true
os:
  - osx
  - windows
  - linux
# 新增的before_install步骤，仅在Linux环境执行依赖安装
before_install:
  - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then sudo apt-get update && sudo apt-get install -y libasound2-dev; fi
script:
  - cargo build --verbose --release
before_deploy:
  - if [[ -f target/release/soundsense-rs ]]; then mv target/release/soundsense-rs "target/release/soundsense-rs-$TRAVIS_TAG-$TRAVIS_OS_NAME"; fi
  - if [[ -f target/release/soundsense-rs.exe ]]; then mv target/release/soundsense-rs.exe "target/release/soundsense-rs-$TRAVIS_TAG-$TRAVIS_OS_NAME.exe"; fi
deploy:
  - provider: releases
    skip_cleanup: true
    on:
      tags: true
      condition: "$TRAVIS_RUST_VERSION = stable"
      branch: release
    file_glob: true
    file:
      - target/release/soundsense-rs-*
